Description
SHURflo pedestal non-metallic pumps produce high flow rates under moderate head conditions.
Designed for continuous medium pressure circulation and transfer of nonflammable liquids, water circulation, booster
service, irrigation, spraying systems, jockey pump service, aggressive liquid applications, and other general-purpose pumping
compatible with pump component materials where no suction lift is required. Water seal flush port is provided for the
decontamination of chemicals on the seal and seat elastomers.
• Capacities to 110 GPM, heads to 95 ft.
• 1/3 to 3 HP AC requirement range.
• Discharge can be rotated in 90-degree intervals.
• All pumps have 11⁄2"female NPT inlet and outlet ports.
• Standard pump models (at 3450 RPM) will handle specific gravities to 1.1 (at 100 SSU or less). For specific gravities to 1.4
(at 100 SSU or less), increase motor HP by one size but not to exceed standard 3 HP motor at 3450 RPM or 65 in.-lbs. of torque
maximum. Higher specific gravity fluids are not recommended.
•Standard pump models (at 3450 RPM) will handle viscosity to 100 SSU (at 1.1 specific gravity or less) and up to 200 SSU
(specific gravity of 1.0 or less). For viscosity up to 400 SSU (specific gravity of 1.0 or less), increase motor HP by one size but not
to exceed standard 3 HP motor at 3450 RPM or 65 in.-lbs. of torque. For fluids with a viscosity greater than 400 SSU, pump
speed must be reduced below 3450 RPM.
• Maximum operating speed is 3600 rpm.
•Pedestal-mount models feature a 5/8" diameter; 316 stainless steel solid shaft; a corrosion-resistant coated cast iron bearing
housing and sealed ball bearings. They may be either long coupled or pulley driven with any base-mounted motor such as
ODP, TEFC or wash-down motors.
CLOSE COUPLED – Non-metallic pumps are also available that feature NEMA 56J frame motors with base.
NORYL SERIES – This series is designed for industrial chemical application. The pumps are made of Noryl, which is non-metallic
and chemical-resistant to most acids, alkalis, and inorganic solvents. This material is stiffer under pressure and temperature than
the Polypropylene Series. Noryl models handle inlet booster pressures to 30 PSI and maximum temperatures up to 180° F. These
pumps are equipped with a unique chemical-resistant, carbon and ceramic mechanical seal with Viton elastomer having the stain-
less steel components sealed in Noryl allowing for a complete non-metallic Noryl wet end. This unique seal guarantees
reliability through simplicity and balance of design. Even the pedestal drive shaft is protected by the seal design.
POLYPROPYLENE SERIES – This series is designed for light industrial or commercial water-based applications. The pumps are
made of non-metallic, glass-filled polypropylene construction offering chemical resistance to most acids, alkalis, and inorganic
solvents as does the Noryl Series. The difference is these pumps are equipped with a carbon ceramic mechanical seal with
Buna-N elastomers with the stainless steel components that are not sealed, but still protect the pedestal shaft from chemical
exposure. The polypropylene series cannot handle added inlet booster pressures and is rated for a maximum temperature of
140°F
.However,upgraded chemical-resistant, polypropylene-encased seals are available.
REPAIR SEALS AND OPTIONS – Standard and upgraded seals are available for both the Noryl and Polypropylene pumps.
If abrasive or small, particulated fluids are being pumped, upgrading to either the encased Noryl or polypropylene silicon
carbide mechanical seal with Viton elastomers is recommended. Standard and upgraded seals can be located on the
repair parts list pages in this manual.
PUMP HEADS AND PEDESTAL MOUNT BASE – Complete pump heads and pedestal base can be ordered. Pump head and
pedestal base model numbers are called out in the repair parts list pages in this manual.
Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable and/or
explosive atmospheres. When pumping hazardous or dangerous materials, use only in room or area designated for that purpose.
For your protection, always wear proper clothing, eye protection, etc. in case of any malfunction. For proper handling techniques and
cautions, contact your chemical supplier, insurance company and local agencies (fire dept., etc.). Failure to comply with this warning could
result in personal injury and/or property damage.
Pumps are not self-priming and cannot suction lift, flooded inlet is required. If inlet is not flooded when the pump is
running, seal failure will result and is not covered under the manufacturer’s warranty.

Make certain
that the unit is
disconnected from the power source
before attempting to service or remove
any components! Do not exceed 3600
rpm operating speed.
Drive Source Installation for
the Pedestal-Mount Pump
This manual covers the installation of
the basic drive configuration for the
pedestal polypropylene and noryl
centrifugal pumps. Consult the
manufacturer of motor or engine for
additional information. Read all
instructions before attempting to
install or operate the pump. The unit
should run clockwise as viewed facing
the shaft end. Counterclockwise rota-
tion can result in damage to the pump
motor, property damage and/or
personal injury.
Safety shields are
required and must be
mounted and kept in place while power is
supplied to pump drive.
BELT/PULLEY DRIVE INSTALLATION
1. For pulley-driven pumps, a single
1/2" [12.7 mm] (A or 4L section)
“V” belt is satisfactory for drive
sizes and speed up to 1 HP, 3450
RPM. For larger sizes, double “V”
belts are recommended.
2. Mount pulleys as close to the
pump and motor engine shaft
bearings as possible. Check the
alignment with a straight edge as
shown in Figure 1. Make sure that
the belt has proper tension. (Too
much tension will cause bearing
wear; too little will cause
slippage). See Figure 2. Check with
belt and pulley sources for specific
recommendation. A safety shield
(belt guard) must be installed over
the motor/pump pulleys and belts.
3. To figure proper diameter of pump
pulley, multiply motor/engine RPM
by the diameter of the
motor/engine pulley and divide
that figure by the desired pump
speed.
Pump
Pulley = Motor RPM x Motor Pulley Size
Size Desired Pump Speed
4. A safety shield (belt shield)
must be installed over the pump and
motor shafts, pulleys and belt.
NOTE: Refer to the pump performance
charts to determine the desired speed
to obtain the desired maximum flow.
Direct Drive - Flexible Coupling
For direct driving of pedestal centrifu-
gal pumps with flexible couplings,
make sure that the speed (RPM) of the
gas engine or electric motor is within
the maximum rated RPM of your
pump. Make sure that shaft rotation is
correct between the pump and the
motor or gas engine (see Figure 3).
1. Mount the motor or engine into
position on the base.
2. Line up the pump shaft with the
straight edge as shown in Figure 4
to assure they are aligned. Shim
the pump if necessary to match the
shaft height of the engine or motor.
The shaft ends should not touch.
3. Mark the exact position of the
pump on the base. Remove and
install the coupling halves on both
shafts. Place the coupling center
disc into one of the coupling halves.
4. Re-position the pump, sliding the
coupling halves together.
NOTE: No end thrust should be applied
to the pump when the coupling is
connected.
5. Tighten the pump mounting and
then the set screws on each coupling.
6. Asafety shield (coupling guard) must
be installed over the pump and
motor shafts and coupling.

Troubleshooting Chart
Pump Installation
Do not run the pump
dry! Check pump
rotation before operating. Pump rotation
should be clockwise as seen from shaft
end. Reverse rotation can result in severe
pump damage.
1. Position the pump as close as possi-
ble to the source being pumped.
Aflooded suction situation is
required. The pump is NOT self-
priming, therefore, if the fluid
level is below the pump, a foot
valve must be installed and the
pump primed prior to start-up.
2. Mount the pedestal base to a
secure, immobile foundation.
3. Use only composite fittings on
both the intake and discharge
ports. Seal the pipe connections
with Teflon™ tape. These fittings
should be self-supported and in
neutral alignment with each port.
Fittings must not be forced into
alignment because it may cause
premature line failure or damage
to the pump housing volute.
4. Never choke the intake. Keep both
input and discharge lines as free of
elbows and valves as much as pos-
sible. Always use an adequate
diameter pipe. This will reduce fric-
tion losses and maximize output.
5. For positive pump start-up upon
intial installation or after pump
has been maintained or fluid
drained from pump, fill pump with
water or liquid compatible with
pumped material. This is accom-
plished by installing a “T” fitting
on the discharge with the fill por-
tion of the fitting facing up.

Maintenance
Make certain
that the unit is
disconnected from the power source
before attempting to service or remove
any components!
REMOVAL OF OLD SEAL ASSEMBLY
Should the mechanical seal (Ref. No. 5)
require repair, proceed as follows and
refer to Figures No. 5 - 7.
IMPORTANT: Always replace both the
seal seat and seal as an assembly to
ensure proper mating of components!
1. Remove bolts (Ref. No. 8) connecting
the pump housing casing (Ref. No. 2)
to the body adapter (Ref. No. 1).
2. Remove the pump housing casing
(Ref. No. 2).
Care should be taken
not to pinch or ”shave”
the O-ring gasket (Ref. No. 6) between the
body adapter and the housing casing.
3. Remove the impeller (Ref. No. 4)
from the shaft by unscrewing it
counterclockwise as viewed from
the pedestal pump face.
NOTE: Pump shaft must be held in
place to remove impeller. Impeller (Ref.
No. 4) unscrews CCW when looking
at the front of the pump.
4. The ceramic seat is located on the
back side of the impeller (part of
Ref. No. 5). Pry the seat out by
using a screwdriver in the inside
hole (see Figure 5). Be careful not
to damage or scratch the inside
surfaces of the bore holding the
seat. Such scratches can cause
leaks. Replace the impeller if such
damage occurs.
5. Remove the body adapter (Ref. No.
1)from the pedestal by removing
the adapter bolts.
6. Use a wooden dowel to push out
the mechanical seal (part of Ref.
No. 5) from the body adapter (Ref.
No. 1). (See Figure 5.) Do not dig
the seal out from the front.
INSTALLATION OF NEW SEAL
ASSEMBLY
The precision
carbon/ceramic faces
on the mechanical seal are easily damaged.
Handle your repair seal carefully. Do not
touch the carbon/ceramic seal faces.
IMPORTANT: Be sure that shaft
shoulder does not damage carbon face.
1. Thoroughly clean all surfaces of the
seal cavity in body adapter (Ref. No. 1).
2. Replace the o-ring inside the cavity
(Ref. No. 11). Using seal installation
tool (see Figure 6), press in new
mechanical seal being careful not
to scratch the polished carbon face.
3. Wet the rubber portion of the new
seal seat (part of Ref. No. 5) with a
light coating of soapy water.While
wearing clean gloves or using a
clean light rag, press seal seat
squarely into impeller recess. Use
the cardboard washer (usually sup-
plied with new seal) to place over
the polished ceramic surface and
use a piece of pipe or dowel rod to
press in firmly but gently (see Figure
5). Avoid scratching the ceramic
face, usually white.
4. Dispose of cardboard washer. Check
again to see that ceramic surface is
free of dirt and all other foreign
particles and that it has not been
scratched or damaged.
5. Install the body adapter (Ref.
No. 1) to the pedestal using bolts.
Be careful not to damage the seal
when sliding over the shaft.
6. While preventing the shaft from
turning, screw impeller (Ref.
No. 4) onto shaft and tighten
(see Figure 5).
NOTE: Ashort “run-in” period may be
necessary to provide completely
leakproof seal operation.
This completes the seal installation.
7. Check if shaft turns freely by spin-
ning impeller. If rubbing or binding
is found, remove impeller.
8. Place o-ring (Ref. No. 6) into groove
on back side of housing. It may be
necessary to temporarily hold the
o-ring in the groove with grease.
Seal assembly will
produce minor drag
when spinning shaft, but rubbing any-
where else must be eliminated! Otherwise,
damage to pump and/or motor may occur.

Water-Flushed Seals
1. Water-flushed seals are recom-
mended for abrasive solutions,
high temperature service, or when
pumps may be run dry or against
deadhead conditions.
2. When conditions cause the pumped
liquid to form crystals, or if the
pump remains idle for a period of
time without adequate flushing, a
water-flush seal system is advised.
3. The water flush will provide decon-
tamination of chemicals on elas-
tomers and seal and seat faces,
while providing lubrication required
for start-up. Two (2) methods of
water flush can be used:
a. Direct Plumbing to City Water
This provides the best possible
approach to flushing the seal and
seat faces. Caution must be taken
to conform to local city ordinances
that may require backflow preven-
ters. These are a series of check
valves required to prevent contam-
ination of city water if the water
supply is shut off. Also be aware of
the addition of water into the
chemicals pumped where some
imbalance may be created, altering
the chemical’s formulation and
aggressiveness.
b. The flush port is provided on the
side of the pump below the dis-
charge.
c. Recirculation of Solution Pumped
This system takes a bleed off the
pump discharge and recirculates
the solution in the seal chamber.
Although not nearly as effective as
the direct water flush, it will
provide cooling to the seal and
seat faces under operation. This
system is not effective where
crystalization occurs or for pumps
in idle conditions.
For internal recirculation to seal,
drill the recess plug on the pump
body located at 3 o’clock with a
1/8” drill.
Hazardous
substance alert!
4. Always drain and flush the pump
before servicing, disassembling
for any reason or returning the
unit for repair.
5. Never store pumps containing
hazardous chemicals.
6. Before returning the pump for
service/repair, drain out all liquids
and flush the unit with a neutraliz-
ing liquid. Then, drain the pump.
Attach a tag or include a written
notice certifying that this has been
done. Please note that it is illegal
to ship or transport any hazardous
chemicals without United States
Environmental Protection Agency
Licensing.
