locatioN

The pump should ideally be placed as close as

possible to the liquid supply source. Allow suffi-

cient space on the sides and overhead to permit

inspection and maintenance work to be performed.

FouNdatioN

The foundation for the pump should be level,

provide rigid support of pump and motor. It should

also be of sufficient mass to dampen any vibra-

tions developed. Typically this is accomplished

by installing and grouting a Fybroc baseplate on

a concrete foundation.

Foundation bolts of the proper size should be

imbedded in the concrete with anti-rotation lugs,

located by a drawing or template (See Table 1

below for bolt-size and locations). A pipe sleeve

larger than the bolt should be used to allow enough

lateral movement for final positioning of the bolts

(See Figure 1 below). Leveling wedges or

shims should be placed under the sides of the

baseplate to level the unit and the foundation

bolts slightly tightened.

A wood form can now be built around the edge of

the baseplate to contain the grout. The top of the

rough concrete foundation should be wetted down

prior to grouting. A good grade of non-shrinking

grout can now be packed through the open end of

the fiberglass baseplate. Once the grout has fully

hardened, usually about 48 hours after pouring,

the foundation bolts can be fully tightened.

pipiNg the pump

All flanged connections to the pump should be full

flat face with full contact gaskets. Raised face

flanges or partial contact gaskets should not be

used as excessive strains can be applied to the

pump flanges upon tightening.

The pump has been designed with all necessary

strength factors for long, reliable service life.

However, due to the composite construction, care

must be taken during installation to avoid unneces-

sary pipe strain. If severe piping strains are to be

encountered, flexible connections are recommended

in the suction and discharge pipe lines. When

lined piping is used, flange alignment should be

carefully checked. Spacer ring gaskets are

recommended to assure parallel alignment of pipe

and pump flanges. The following flange bolt torque

values should be used:

All piping must be supported independently of the

pump. The piping should always line up naturally

with the pump flanges. Never draw the piping to

the suction or discharge flanges of the pump.

Outside installations should be properly compen-

sated for changes in ambient temperatures. Refer

to pipe manufacturers standards for proper

installation. Omission of this could result in severe

strain transmitted to the pump flanges.

The piping should be as short and direct as possible.

Avoid all unnecessary elbows, bends and fittings,

as they increase friction losses in the piping.

suctioN pipiNg

A) To minimize friction loss, the length of the suction

pipe (from process to pump inlet) should be as

short as possible. It is important that NPSH

available to the pump is greater than the

NPSH required by the pump, long suction runs

greatly affect NPSH and should be considered

carefully. See pump performance curve for

NPSH requirements.

B) The diameter of the suction pipe should be as

large as the pump suction. If long suction runs

are encountered, the suction pipe diameter

should be increased to reduce the NPSH

required.

C) Increasers or reducers, if used, should be

eccentric and installed with the eccentric side

on the bottom of the pipe to prevent air traps.

D) Elbows, fittings, valves or expansion joints

should be avoided at the suction flange. Allow

a straight run of at least 10 pipe diameters into

the suction of the pump.

E) If a valve is to be installed in the suction

piping, only full flow valves offering a minimum

flow disturbance should be used (ball, plug

types). These valves should be for shut-off

only when the pump is not running, and not for

throttling or controlling flow. Centrifugal pumps

should never be throttled on the suction side.

F) Provisions for a suction pressure gauge should

be included.

discharge pipiNg

A) Installation of a valve in the discharge line that

can be used as a block for inspection and

maintenance is recommended. It should be of

a design to allow throttling or flow control.

B) The diameter of the discharge pipe should be

as large or larger than the pump discharge.

C) Provision for a discharge pressure gauge

should be included.

aNcillary pipiNg

A) The diameter of the ancillary or seal piping

should be large enough to meet the seal flush-

ing requirements. Typically this is 1/4-1/2 GPM

at a pressure of 15-25 PSI above the suction

pressure for most mechanical seals. Refer to

pages 25 and 26 for recommended seal flush

flow rates and piping installations.

B) Where the ancillary piping is connected to the

pump only plastic fittings shall be used.

WarNiNg: Failure to use plastic

FittiNgs may result iN damage to

the pump.

C) Many modern flush systems incorporate elec-

trically actuated solenoid valves to conserve

and control the flow of flush liquids, ensure that

the flush liquid is flowing to the seal before the

pump is started.

D) On double seal arrangements with flush in and

flush out connections, flow control valves

should be installed in the flush out or down-

stream side.

The pump shaft should turn freely by hand after

the piping has been connected to the pump. This

is to insure that the piping has not caused binding

in the pump. If binding occurs, check for cause

and correct.

electrical coNNectioNs

All electrical work done to the unit should be

done by a qualified electrician. All local, state and

federal electrical codes should be adhered to.

B) Wire motor according to motor manufacturers

instructions. Ensure that all connections and

covers are tight and that proper sized wire and

switch-gear are used.

C) All pumps operate in a clockwise direction

when viewed from the motor end, (see

direction arrow on the pump motor adapter).

Connect electric motor to power supply and jog

motor to check rotation. If motor is operating

in wrong direction, reverse leads and recheck.

lubricatioN

On a close coupled pump only the motor requires

lubrication. Since all motors come from the factory

pre-lubricated there is no action required.

seal FlushiNg

Mechanical Seals

Do not operate the pumps without liquid to the

mechanical seal. Depending on the flush arrange-

ment of the pump, the fluid to the seal may be

piped from the pump discharge externally or

internally, or from an external clean source. If the

pump is fitted with an internal or bypass flush

arrangement, then the pump must be flooded

with liquid prior to starting to ensure that the

mechanical seal is lubricated. If the pump is

equipped for an external flush system, then flush

liquid must be supplied to the seal prior to starting.

Proper flow for external flushing will vary from 1/4

to 1/2 GPM at a pressure of 15 to 25 PSI above

the stuffing box pressure.

primiNg

Suction valve must be fully open. The pump cas-

ing and suction pipe must always be full of liquid

before the pump is started. Centerline discharge

designs are self-venting therefore the discharge

valve should be opened to release any air trapped

in the pump and then left slightly open at start-up.

startiNg

Prior to starting, turn pump shaft by hand to be

sure rotating elements are free. If it rubs or binds:

A Check for piping strains on casing flanges,

or other loads on casing.

B) Check impeller clearance.

(See impeller adjustment).

Prior to starting pump recheck installation proce-

dures with the operational start-up checklist found

on page 14 of this manual.

Start pump and bring up to speed, open discharge

valve to the rated flow.

maiNteNaNce

Fybroc pumps are designed for a long service

life. The only scheduled maintenance items are

the lubrication intervals for the motor. Please

refer to the lubrication procedures given below.

motor

The motor relubrication intervals are greatly influ-

enced by the environment it is in and the length of

time it runs. Refer to the following chart for typical

relubrication values for motors. Standard duty is

when the motor is operated eight hours a day and

the environment is free from dust. Severe duty is

when the motor runs twenty-four hours per day

with exposure to dirt and dust.

geNeral

The Fybroc pump is designed for easy inspection

and service because of its back pullout construc-

tion. For inspection or replacement of certain

parts, the work can be done in place, without the

necessity to remove the complete pump to a

maintenance area. Refer to applicable Sectional

Drawing in this manual for item numbers

mentioned below.

Before any work is done the following procedures

and precautions should be taken:

1) The electric motor should be either disconnected

from its power source, or the switch or circuit

breaker must be secured in an “off” position so

that the motor cannot be accidentally started.

2) Depending upon the fluid being pumped, the

proper protective equipment should be worn

(gloves, mask, respirator, goggles or safety

glasses, etc.) to prevent contact with the fluid

in the pump or pipelines.

3) Check the valves on the suction and discharge

lines to be sure they are closed and secured.

4) If the mechanical seal is flushed from an exter-

nal source, turn off the valve in the supply line

and disconnect the flush line.

5) The liquid trapped in the pump and piping should

be drained. Care should be taken to either trap

the fluid in a container or to divert it to a proper

disposal area so that the area around the pump

and base will not be contaminated.

disassembly

1) If the complete pump is to be removed to a

maintenance area, remove the bolts holding

the motor and casing to the baseplate. Remove

the bolts on the suction and discharge flange

connections. Now the whole pump can be

removed. If the casing is to be left in place

remove the screws holding the motor to the

baseplate and then remove the casing bolts,

nuts, washers and shims securing the casing

to the cover and motor adapter (Items 1C,

1D, 1E, 67). Now the rotating assembly can

be pulled away from the casing and removed.

Note the number of shims removed. Two

jackscrews (Item 19D) are provided to

ease disassembly.

If the casing was removed with the pump,

remove the casing bolts, nuts, washers and

shims securing the casing to the cover and

frame adapter (Items 1C, 1D, 1E, 67). The

rotating assembly can be pulled away from

casing. Note the number of shims that were

removed. Two jackscrews (Item 19D) are

provided to ease disassembly. Now the pump

can be placed in a convenient location to

disassemble it.

Remove the cover o-ring (Item 73) and place in

a container with the casing hardware.

To disassemble the impeller assembly, remove

the locking ring (Item 14 B) by removing the

two Allen head screws, thus exposing the

segment key (Item 14A), which can now be

removed from the impeller sleeve.

If the pump is provided with a mechanical seal

utilizing set screws to drive the seal, loosen the

set screws. If the mechanical seal is of the

preset outside type, reinstall the seal setting

clips, prior to loosening the set screws.

Remove rear fan cover from motor; use vise

grips or pipe wrench to hold rear motor shaft

extension from turning. Remove fan if required.

Do not attempt to hold fan. The impeller

assembly can now be removed by turning the

impeller in a counter-clockwise direction facing

the impeller. A strap wrench or similar device

may be required to disengage the screw

threads. The impeller, stuffing box cover, and

seal can now be removed as a unit.

If the mechanical seal is a single outside seal

be sure the set screws are loose and pull the

rotary seal assembly off the sleeve, using a

twisting motion as it is removed. The impeller

(Item 2) can be removed from the cover.

Remove the four bolts and washers (Item 17C,

17E) securing the gland (Item 17) to the cover

(Item 11) and remove the gland and then the

seal stationary from the cover. The carbon and

ceramic elements of the seal should be handled

carefully to prevent chipping or scratching.

ASSEMBLY/ DISASSEMBLY PROCEDURES FOR HORIZONTAL PUMPS

The close coupled 1530 series design allows

adjustment of the impeller clearance between the

pump casing wall and the impeller face. The pump

impeller is adjusted at the factory during assembly

and should not require further adjustment upon

installation.

Impeller adjustment will be required when a drop

in head and/or capacity indicates a change in

clearances, or when existing components of the

pump are replaced. Refer to the following table for

recommended clearance when adjusting impeller

on horizontal pumps.

1) When existing components of the pump are

replaced with the exception of the casing, refer

to the assembly section of this manual for

proper impeller adjustment.

2) For impeller adjustment to compensate for

wear follow the procedure below.

A) Lock out the switch or circuit breaker in

the “OFF” position so that the motor can-

not be accidentally started.

B) Loosen set screws or other holding

devices if so provided on mechanical

seals before adjusting impeller to prevent

seal face damage.

C) Loosen bolts holding motor to base and

loosen casing bolts (Item 1D). Remove

fan guard.

D) Remove one shim (Item 67) from each

side of pump by pulling outward on the

extended tabs; this will decrease the

impeller front clearance by .010". Slowly

retighten casing bolts while turning and

pushing forward on the motor shaft to

be sure no binding occurs. If binding

occurs from the impeller rubbing the

casing, the shims that were removed

will have to be replaced

E) Continue this procedure until the impeller

1013

Impeller Diameter Clearance

starts to contact the casing. At this point

replace the appropriate number of shims

to obtain the approximate impeller clear-

ance shown in the table above.

F) Reset and tighten the mechanical seal

per the seal manufacturers instructions

and retighten the motor mounting bolts.

Replace fan guard.

IMPELLER ADJUSTMENT If the mechanical seal is a double inside seal,

remove the four bolts and washers (Item 17C,

17E) securing the gland (Item 17) to the cover

(Item 11) and remove the gland. Be sure the

set screws are loose, and pull the rotary seal

assembly off, using a twisting motion as it is

removed. The impeller (Item 2) can be

removed from the cover. Next remove the

stationary seal faces from the gland and

cover by gently pressing them out using your

thumbs. The carbon and ceramic elements

of the seal should be handled carefully to

prevent chipping or scratching.

The motor shaft adapter (Item 6) may be

removed from the motor shaft by removing the

Allen head screw (Item 6A). The drive key

(Item 46) will slide off with the shaft adapter.

In the bore of the shaft adapter there may be

some shims to take up the motor manufactur-

er’s shaft length tolerances. Be sure to note

the number and thickness of the shims used.

Remove pump adapter (Item 71) and motor

adapter (Item 71B) if provided.

assembly

1) Inspect casing, cover and impeller for any

damage and make sure all sealing surfaces

are free of dirt and scratches. If pump is

equipped with an internal seal flush, make

sure cover flush hole is clear. Check motor

end float. Excessive shaft end float (greater

than .015") can result in damage to pump

and or mechanical seal.

2) If equipped install the motor adapter (Item 71B).

Ensure that the adapter is seated squarely on

the motor before tightening adapter screws,

this may require some sanding of the paint on

the pilot diameters. Secure with adapter

screws (Item 71C), torque to 25 ft-lbs.

3) Install the pump adapter (Item 71). Ensure

that the adapter is seated squarely on the

motor adapter or motor before tightening

adapter screws, this may require some sand-

ing of the paint on the pilot diameters. Secure

with adapter screws (Item 71A), torque to

25 ft-lbs.

end of shaft.

4) Place one .062" shim washer (Item 6B) in the

shaft (Item 6) bore. Install key (Item 46) into

the shaft key-way slot from the inside of the

shaft bore. Slide assembly onto motor shaft

and temporarily secure with shaft screw

(Item 6A).

5) Place six impeller adjusting shims (Item 67,

three on each side) and the cover (Item 11) on

to the pump adapter. Ensure that the cover is

seated squarely on the pump adapter, this may

require some sanding of the paint on the pilot

diameter. Clamp the cover tightly to the

adapter with clamps or bolts.

6) Thread the impeller (Item 2) onto the shaft

adapter until it bottoms on the shoulder of

the shaft adapter. Place a feeler gauge

between the cover and the balance vanes

on the impeller.

7) The gauge should read approximately .035", if

it does not, repeat steps 4-6 using a different

washer or combination of washers until the

proper clearance is obtained. Four washers

are supplied by Fybroc: [email protected]", [email protected]"

and [email protected]" this will provide for 0-.110" worth

of shimming capabilities which will adapt to any

motor used.

8) Once the proper number of shims is deter-

mined, remove the impeller, cover and plastic

shims and tighten the shaft adapter screw to

35 ft-lbs. for 3/8" screws and 50 ft-lbs. for

1/2" screws.

9) Place some anti-seize lubricant on the shaft

adapter impeller threads.

10) The Fybroc pump, as standard, is equipped with

a single outside seal with stationary seal face

and rotating compression unit, or a double

inside seal with stationary seal faces and rotat-

ing double seal compression unit. The following

installation instructions are based on these seal

types. When other types of seals are used,

please refer to the manufacturer's installation

data. Determine the type of seal being used and

refer to the following sections.

2) Install the inboard stationary gasket and the

stationary seal insert into their bores on the

pump cover. Then place the outboard stationary

gasket over the stationary insert. Next place

the seal gland over the stationary insert and

gaskets, making sure that all the gaskets have

been installed properly before securing the

gland bolts. Be sure that the gland pilot is

properly engaged, and draw up the gland bolts

evenly, cross staggering adjustment of the

bolts. Proper gland bolt adjustment is especially

important where clamp style inserts are used.

The gland bolts should be torqued to a

maximum of 10 ft/lbs.

3) Lightly coat the impeller sleeve with a suitable

lubricant. Carefully slide impeller sleeve

through the cover, being careful not to chip

the stationary sealing face.

4) Lubricate the rotary unit o-ring with a suitable

lubricant. Then engage the rotary assembly

over the impeller sleeve. Use a slight twisting

motion as the rotary unit is slid down the

impeller sleeve until it touches the stationary

sealing face. Do not tighten set screws or

remove setting clips.

5) Mount the impeller, cover and seal assembly

onto the pump adapter, making sure the

impeller threads are firmly bottomed on the

shaft threads. Install the cover shims (Item 67)

between the pump adapter and cover.

6) Install the segment key (Item 14A) in the corre-

sponding slot at the rear of the impeller sleeve.

The close coupled 1530 series design allows

adjustment of the impeller clearance between the

pump casing wall and the impeller face. The pump

impeller is adjusted at the factory during assembly

and should not require further adjustment upon

installation.

Impeller adjustment will be required when a drop

in head and/or capacity indicates a change in

clearances, or when existing components of the

pump are replaced. Refer to the following table for

recommended clearance when adjusting impeller

on horizontal pumps.

1) When existing components of the pump are

replaced with the exception of the casing, refer

to the assembly section of this manual for

proper impeller adjustment.

2) For impeller adjustment to compensate for

wear follow the procedure below.

A) Lock out the switch or circuit breaker in

the “OFF” position so that the motor can-

not be accidentally started.

B) Loosen set screws or other holding

devices if so provided on mechanical

seals before adjusting impeller to prevent

seal face damage.

C) Loosen bolts holding motor to base and

loosen casing bolts (Item 1D). Remove

fan guard.

D) Remove one shim (Item 67) from each

side of pump by pulling outward on the

extended tabs; this will decrease the

impeller front clearance by .010". Slowly

retighten casing bolts while turning and

pushing forward on the motor shaft to

be sure no binding occurs. If binding

occurs from the impeller rubbing the

casing, the shims that were removed

will have to be replaced

E) Continue this procedure until the impeller

assembly off, using a twisting motion as it is

removed. The impeller (Item 2) can be

removed from the cover. Next remove the

stationary seal faces from the gland and

cover by gently pressing them out using your

thumbs. The carbon and ceramic elements

of the seal should be handled carefully to

prevent chipping or scratching.

The motor shaft adapter (Item 6) may be

removed from the motor shaft by removing the

Allen head screw (Item 6A). The drive key

(Item 46) will slide off with the shaft adapter.

In the bore of the shaft adapter there may be

some shims to take up the motor manufactur-

er’s shaft length tolerances. Be sure to note

the number and thickness of the shims used.

Remove pump adapter (Item 71) and motor

adapter (Item 71B) if provided.

assembly

1) Inspect casing, cover and impeller for any

damage and make sure all sealing surfaces

are free of dirt and scratches. If pump is

equipped with an internal seal flush, make

sure cover flush hole is clear. Check motor

end float. Excessive shaft end float (greater

than .015") can result in damage to pump

and or mechanical seal.

2) If equipped install the motor adapter (Item 71B).

Ensure that the adapter is seated squarely on

the motor before tightening adapter screws,

this may require some sanding of the paint on

the pilot diameters. Secure with adapter

screws (Item 71C), torque to 25 ft-lbs.

3) Install the pump adapter (Item 71). Ensure

that the adapter is seated squarely on the

motor adapter or motor before tightening

adapter screws, this may require some sand-

ing of the paint on the pilot diameters. Secure

with adapter screws (Item 71A), torque to

end of shaft.

4) Place one .062" shim washer (Item 6B) in the

shaft (Item 6) bore. Install key (Item 46) into

the shaft key-way slot from the inside of the

shaft bore. Slide assembly onto motor shaft

and temporarily secure with shaft screw

(Item 6A).

5) Place six impeller adjusting shims (Item 67,

three on each side) and the cover (Item 11) on

to the pump adapter. Ensure that the cover is

seated squarely on the pump adapter, this may

require some sanding of the paint on the pilot

diameter. Clamp the cover tightly to the

adapter with clamps or bolts.

6) Thread the impeller (Item 2) onto the shaft

adapter until it bottoms on the shoulder of

the shaft adapter. Place a feeler gauge

between the cover and the balance vanes

on the impeller.

7) The gauge should read approximately .035", if

it does not, repeat steps 4-6 using a different

washer or combination of washers until the

proper clearance is obtained. Four washers

are supplied by Fybroc: [email protected]", [email protected]"

and [email protected]" this will provide for 0-.110" worth

of shimming capabilities which will adapt to any

motor used.

8) Once the proper number of shims is deter-

mined, remove the impeller, cover and plastic

shims and tighten the shaft adapter screw to

35 ft-lbs. for 3/8" screws and 50 ft-lbs. for

1/2" screws.

9) Place some anti-seize lubricant on the shaft

adapter impeller threads.

10) The Fybroc pump, as standard, is equipped with

a single outside seal with stationary seal face

and rotating compression unit, or a double

inside seal with stationary seal faces and rotat-

ing double seal compression unit. The following

installation instructions are based on these seal

types. When other types of seals are used,

please refer to the manufacturer's installation

data. Determine the type of seal being used and

refer to the following sections.

geNeral

The Fybroc pump is designed for easy inspection

and service because of its back pullout construc-

tion. For inspection or replacement of certain

parts, the work can be done in place, without the

necessity to remove the complete pump to a

maintenance area. Refer to applicable Sectional

Drawing in this manual for item numbers

mentioned below.

Before any work is done the following procedures

and precautions should be taken:

1) The electric motor should be either disconnected

from its power source, or the switch or circuit

breaker must be secured in an “off” position so

that the motor cannot be accidentally started.

2) Depending upon the fluid being pumped, the

proper protective equipment should be worn

(gloves, mask, respirator, goggles or safety

glasses, etc.) to prevent contact with the fluid

in the pump or pipelines.

3) Check the valves on the suction and discharge

lines to be sure they are closed and secured.

4) If the mechanical seal is flushed from an exter-

nal source, turn off the valve in the supply line

and disconnect the flush line.

5) The liquid trapped in the pump and piping should

be drained. Care should be taken to either trap

the fluid in a container or to divert it to a proper

disposal area so that the area around the pump

and base will not be contaminated.

disassembly

1) If the complete pump is to be removed to a

maintenance area, remove the bolts holding

the motor and casing to the baseplate. Remove

the bolts on the suction and discharge flange

connections. Now the whole pump can be

removed. If the casing is to be left in place

remove the screws holding the motor to the

baseplate and then remove the casing bolts,

nuts, washers and shims securing the casing

to the cover and motor adapter (Items 1C,

1D, 1E, 67). Now the rotating assembly can

be pulled away from the casing and removed.

Note the number of shims removed. Two

jackscrews (Item 19D) are provided to

ease disassembly.

If the casing was removed with the pump,

remove the casing bolts, nuts, washers and

shims securing the casing to the cover and

frame adapter (Items 1C, 1D, 1E, 67). The

rotating assembly can be pulled away from

casing. Note the number of shims that were

removed. Two jackscrews (Item 19D) are

provided to ease disassembly. Now the pump

can be placed in a convenient location to

disassemble it.

Remove the cover o-ring (Item 73) and place in

a container with the casing hardware.

To disassemble the impeller assembly, remove

the locking ring (Item 14 B) by removing the

two Allen head screws, thus exposing the

segment key (Item 14A), which can now be

removed from the impeller sleeve.

If the pump is provided with a mechanical seal

utilizing set screws to drive the seal, loosen the

set screws. If the mechanical seal is of the

preset outside type, reinstall the seal setting

clips, prior to loosening the set screws.

Remove rear fan cover from motor; use vise

grips or pipe wrench to hold rear motor shaft

extension from turning. Remove fan if required.

Do not attempt to hold fan. The impeller

assembly can now be removed by turning the

impeller in a counter-clockwise direction facing

the impeller. A strap wrench or similar device

may be required to disengage the screw

threads. The impeller, stuffing box cover, and

seal can now be removed as a unit.

If the mechanical seal is a single outside seal

be sure the set screws are loose and pull the

rotary seal assembly off the sleeve, using a

twisting motion as it is removed. The impeller

(Item 2) can be removed from the cover.

Remove the four bolts and washers (Item 17C,

17E) securing the gland (Item 17) to the cover

(Item 11) and remove the gland and then the

seal stationary from the cover. The carbon and

ceramic elements of the seal should be handled

carefully to prevent chipping or scratching.

lubricatioN

On a close coupled pump only the motor requires

lubrication. Since all motors come from the factory

pre-lubricated there is no action required.

seal FlushiNg

Mechanical Seals

Do not operate the pumps without liquid to the

mechanical seal. Depending on the flush arrange-

ment of the pump, the fluid to the seal may be

piped from the pump discharge externally or

internally, or from an external clean source. If the

pump is fitted with an internal or bypass flush

arrangement, then the pump must be flooded

with liquid prior to starting to ensure that the

mechanical seal is lubricated. If the pump is

equipped for an external flush system, then flush

liquid must be supplied to the seal prior to starting.

Proper flow for external flushing will vary from 1/4

to 1/2 GPM at a pressure of 15 to 25 PSI above

the stuffing box pressure.

primiNg

Suction valve must be fully open. The pump cas-

ing and suction pipe must always be full of liquid

before the pump is started. Centerline discharge

designs are self-venting therefore the discharge

valve should be opened to release any air trapped

in the pump and then left slightly open at start-up.

startiNg

Prior to starting, turn pump shaft by hand to be

sure rotating elements are free. If it rubs or binds:

A Check for piping strains on casing flanges,

or other loads on casing.

B) Check impeller clearance.

(See impeller adjustment).

Prior to starting pump recheck installation proce-

dures with the operational start-up checklist found

on page 14 of this manual.

maiNteNaNce

Fybroc pumps are designed for a long service

life. The only scheduled maintenance items are

the lubrication intervals for the motor. Please

refer to the lubrication procedures given below.

motor

The motor relubrication intervals are greatly influ-

enced by the environment it is in and the length of

time it runs. Refer to the following chart for typical

relubrication values for motors. Standard duty is

when the motor is operated eight hours a day and

the environment is free from dust. Severe duty is

when the motor runs twenty-four hours per day

with exposure to dirt and dust.

All piping must be supported independently of the

pump. The piping should always line up naturally

with the pump flanges. Never draw the piping to

the suction or discharge flanges of the pump.

Outside installations should be properly compen-

sated for changes in ambient temperatures. Refer

to pipe manufacturers standards for proper

installation. Omission of this could result in severe

strain transmitted to the pump flanges.

The piping should be as short and direct as possible.

Avoid all unnecessary elbows, bends and fittings,

as they increase friction losses in the piping.

suctioN pipiNg

A) To minimize friction loss, the length of the suction

pipe (from process to pump inlet) should be as

short as possible. It is important that NPSH

available to the pump is greater than the

NPSH required by the pump, long suction runs

greatly affect NPSH and should be considered

carefully. See pump performance curve for

NPSH requirements.

B) The diameter of the suction pipe should be as

large as the pump suction. If long suction runs

are encountered, the suction pipe diameter

should be increased to reduce the NPSH

required.

C) Increasers or reducers, if used, should be

eccentric and installed with the eccentric side

on the bottom of the pipe to prevent air traps.

D) Elbows, fittings, valves or expansion joints

should be avoided at the suction flange. Allow

a straight run of at least 10 pipe diameters into

the suction of the pump.

E) If a valve is to be installed in the suction

piping, only full flow valves offering a minimum

flow disturbance should be used (ball, plug

types). These valves should be for shut-off

only when the pump is not running, and not for

throttling or controlling flow. Centrifugal pumps

should never be throttled on the suction side.

F) Provisions for a suction pressure gauge should

be included.

discharge pipiNg

A) Installation of a valve in the discharge line that

can be used as a block for inspection and

maintenance is recommended. It should be of

a design to allow throttling or flow control.

B) The diameter of the discharge pipe should be

as large or larger than the pump discharge.

C) Provision for a discharge pressure gauge

should be included.

aNcillary pipiNg

A) The diameter of the ancillary or seal piping

should be large enough to meet the seal flush-

ing requirements. Typically this is 1/4-1/2 GPM

at a pressure of 15-25 PSI above the suction

pressure for most mechanical seals. Refer to

pages 25 and 26 for recommended seal flush

flow rates and piping installations.

B) Where the ancillary piping is connected to the

pump only plastic fittings shall be used.

WarNiNg: Failure to use plastic

FittiNgs may result iN damage to

the pump.

C) Many modern flush systems incorporate elec-

trically actuated solenoid valves to conserve

and control the flow of flush liquids, ensure that

the flush liquid is flowing to the seal before the

pump is started.

D) On double seal arrangements with flush in and

flush out connections, flow control valves

should be installed in the flush out or down-

stream side.

The pump shaft should turn freely by hand after

the piping has been connected to the pump. This

is to insure that the piping has not caused binding

in the pump. If binding occurs, check for cause

and correct.

locatioN

The pump should ideally be placed as close as

possible to the liquid supply source. Allow suffi-

cient space on the sides and overhead to permit

inspection and maintenance work to be performed.

FouNdatioN

The foundation for the pump should be level,

provide rigid support of pump and motor. It should

also be of sufficient mass to dampen any vibra-

tions developed. Typically this is accomplished

by installing and grouting a Fybroc baseplate on

a concrete foundation.

Foundation bolts of the proper size should be

imbedded in the concrete with anti-rotation lugs,

located by a drawing or template (See Table 1

below for bolt-size and locations). A pipe sleeve

larger than the bolt should be used to allow enough

lateral movement for final positioning of the bolts

(See Figure 1 below). Leveling wedges or

shims should be placed under the sides of the

baseplate to level the unit and the foundation

bolts slightly tightened.

A wood form can now be built around the edge of

the baseplate to contain the grout. The top of the

rough concrete foundation should be wetted down

prior to grouting. A good grade of non-shrinking

grout can now be packed through the open end of

the fiberglass baseplate. Once the grout has fully

hardened, usually about 48 hours after pouring,

the foundation bolts can be fully tightened.

pipiNg the pump

All flanged connections to the pump should be full

flat face with full contact gaskets. Raised face

flanges or partial contact gaskets should not be

used as excessive strains can be applied to the

pump flanges upon tightening.

The pump has been designed with all necessary

strength factors for long, reliable service life.

However, due to the composite construction, care

must be taken during installation to avoid unneces-

sary pipe strain. If severe piping strains are to be

encountered, flexible connections are recommended

in the suction and discharge pipe lines. When

lined piping is used, flange alignment should be

carefully checked. Spacer ring gaskets are

recommended to assure parallel alignment of pipe

and pump flanges. The following flange bolt torque

values should be used:
