WARRANTY

Gusher Pumps, Inc. will replace or repair, within one year of shipment from our plant, any pump in our judgement that has

failed due to defects in materials or workmanship, provided the pump has been properly installed and maintained and has

not been subject to abuse. These pumps must return to Gusher Pumps, Inc. with complete history of service for inspection

and warranty consideration. Gusher Pumps, Inc. does not accept the responsibility for transportation to and from our plant.

Furthermore, we do not assume any responsibility for consequential damage or loss of production.

RECEIVING AND INSPECTION

The utmost care has been taken at the factory to assure

proper Coupling Alignment and Impeller Adjustment.

However, due to circumstances beyond our control,

YOU MUST inspect the pump upon receipt and follow

the Installation Instructions completely before start-up.

RECEIVING:

1. Rotate shaft by hand. If it does not rotate freely:

a. Check Impeller adjustment.

b. Check for bent Coupling Guard.

c. Check Slinger (#8).

d. Check for bent Shaft (#I).

2. Check for cracked or damaged parts. If upon re-

ceipt, you ﬁnd the pump damaged, ﬁle a claim with

the delivering carrier.

3. If drive motor has been supplied, check the R.P.M.

and Horsepower to be sure it is correct as ordered.

4. Check the Pump Name Tag to be sure we have

shipped correctly as ordered:

a. Model No.

b. Head in feet (Ft. Hd.)

c. Gallons per minute (G.P.M.)

d. Construction:

1. All Iron.

2. All Iron with Stainless Steel Shaft and Impeller.

3. All Stainless Steel.

5. If there is anything that appears to be incorrect, call

the factory immediately.

INSTALLATION

After careful preliminary inspection, you may proceed

with the installation of the pump into your system.

1. Lower the Pump into position.

2. Make sure Mounting Plate (#37) is setting ﬁrmly on

support channels. (It may be necessary to use metal

shims to level plate.)

3. Secure Mounting Plate (#37) by using hold-down

screws in all four corners. Again, care must be taken

to make sure plate is ﬁrm and level. DO NOT force

bowed plate level. Use metal shims if necessary.

4. Make pipe connections:

a. Extreme care must be taken to support piping

without causing any strain on the Pump.

b. Install pipe hangers on discharge pipe so all pip-

ing weight is supported by the hanger and not by

the pump piping or casing.

c. Bolt holes must line-up without prying to insert

bolts.

d. When tightening Flange Bolts, pipe ﬂanges must

not be forced together.

e. Check Valve should be placed in discharge line

between Gate Valve and Pump discharge pipe

to prevent liquid from running back through the

Pump and causing reverse rotation. This is ex-

tremely important in applications with intermittent

duty where the Pump may be rotating backwards

when service is resumed. This will cause damage

to the Pump and the Drive Motor.

f. Pressure gauge should be located at the Pump

Discharge, as all performance data is taken at

pump discharge.

g. If intake piping is used to pump the tank down,

It must also be supported independently of the

Pump.

5. Remove Coupling Guard and rotate Coupling by

hand. Pump should rotate freely at this point. If it

does not, check for:

a. Piping Strain: without exception, piping must not

rest on Pump in any manner. (See Item #4 of IN-

STALLATION.)

b. Impeller Adjustment:

1. Disconnect Coupling (#32) and remove

Sleeve (#32a).

2. Loosen three (3) Locking Screws (#57).

3. Loosen three (3) Adjusting Screws (#55).

4. Lightly tap Shaft (#I) until Impeller (#12)

bottoms on Intake Flange (#13) or Impeller

Housing (#11).

5. Tighten three (3) Adjusting Screws by hand

until they touch Ball Bearing Housing (#5).

6. Tighten three (3) Adjusting Screws 1/4turn

(approximately .016”) by alternating from

one screw to the next, until all three screws

have been turned 1/4turn.

7. Tighten Locking Screws (#57) and Jamb

Nuts (#56).

8. Rotate Coupling by hand to be sure Impel-

ler (#12) does not rub Intake Flange (#13) or

Impeller Housing (#11). If Impeller does rub,

repeat steps #1 through #7.

9. Connect Coupling.

c. Slinger Adjustment: Slinger (#8) is set at Plant

and normally causes no problems, but should be

checked when Unit is inspected upon arrival at

your plant site and before Unit is lowered into po-

sition in your system.

d. Coupling alignment -SEE ITEM #6 below:

6. Coupling Alignment: MUST BE CHECKED before and

after system start-up.

a. Check parallel alignment by placing a straight-

edge across the two coupling ﬂanges and measur-

ing the maximum offset at various points around

the periphery of the coupling. DO NOT rotate the

Coupling. If the maximum offset exceeds .O10”,

realign the Coupling.

b. Check angular alignment with a micrometer or

caliper. Measure from the outside of the one

ﬂange to the outside of the other at intervals

around the periphery of the Coupling. Determine

the maximum and minimum dimensions. DO NOT

rotate the Coupling. The difference between the

maximum and minimum must not exceed .O10”.

If a correction is necessary, be sure to recheck

the parallel alignment.

c. If Coupling Alignment is out, adjustment can

be made with the use of Gusher’s unique Jack

Screw design:

1. LATERAL PARALLEL MISALIGNMENT is ad-

justed by loosening four (4) Motor Screws,

after which you loosen the Lateral Adjusting

Screw (#58) on side of the Motor that has to

be shifted and tighten the remaining Lateral

Adjusting Screw until Lateral Parallel Align-

ment is achieved. (SEE Fig. #3). Tighten all

screws and jamb nuts.

2. HORIZONTAL PARALLEL MISALIGNMENT

is adjusted by loosening four (4) Jack Screw

Jamb Nuts (#50) on back of Chair (SEE Fig. 2)

and turning four (4) Jack Screws (#49) clock-

wise to move Motor away from Chair (#34)

or counter-clockwise to bring Motor toward

Chair. Turn all four (4) Jack Screws equally

so as to maintain proper angular alignment.

Tighten four (4) Jack Screw Jamb Nuts (#50).

3. LATERAL ANGULAR MISALIGNMENT is ad-

justed by loosening four (4) Motor Screws,

after which you loosen the Angular Alignment

Screw (#59) on side of Motor that has to be

lowered and tighten the Angular Alignment

Screw on side of Motor that has to be raised,

until Angular Alignment is achieved. Tighten

all Screw Jamb Nuts. (See Fig. 3).

4. HORIZONTAL ANGULAR MISALIGNMENT

is adjusted by loosening four (4) Jack Screw

Jamb Nuts (#50) on back of Chair (SEE Fig.

#2) and turning two (2) Top Jack Screws

clockwise if top of Motor has to be moved

away from Chair or counter-clockwise if top

of Motor has to be moved toward the Chair.

Tighten Jamb Nuts.

Adjustments can be made with two Bottom

Jack Screws following the same procedure.

NOTES:

1. DO NOT LOOSEN FOUR MOTOR SCREWS

TOO MUCH AS THIS WILL CAUSE DIF-

FICULTY WHEN TRYING TO ALIGN COU-

PLING. Motor Screws must be snug so a

slight force must be applied to move Motor.

Fig. 2

Fig. 3

2. If an adjustment in either Parallel or Angular Align-

ment is required, you must check both after ad-

justment has been made.

3. Coupling alignment must be checked after sys-

tem has been operating for 300 hours. Then as

a Preventative Maintenance Procedure, it should

be checked every 1200 hours of normal opera-

tion. More severe duty operation requires more

frequent attention.

7. Make electrical connection to conform with State

and Local Codes. (It is advisable to use approxi-

mate 4’ length of ﬂexible conduit to facilitate removal

of Chair, if repair is required.)

Upon initial start-up, Pumps may seem to run tight and

hot. This is caused by breaking-in of Oil Seals and Ball

Bearings. Pump will operate normally after approxi- mate-

ly 150 hours of service. Ball Bearings should not run over

225OF. When checking temperature use a pyrometer.

MAINTENANCE

1. Lubrication-All Pumps are lubricated at the Gusher

Plant and should not require additional lubrication

for approximately 1200 hours of operation. A well

planned maintenance schedule can only be devised

after careful observation of the Pump for the ﬁrst

six months of operation and the lubrication that has

been required. Each Pump installation is unique and

requires a different lubrication schedule compatible

with that speciﬁc operation. Use Chevron SRI #2 Ball

Bearing Grease. DO NOT OVER-GREASE as it will

cause ball bearing to run hot.

To Lubricate:

a. Remove Pipe Plug from back of Ball Bearing

Housing (#5).

b. Fill with grease until fresh grease ﬂows from

opening.

c. If automatic lubrication system is being used,

reliefs must be placed in the tapped hole (1/8”

N.P.T.).

2. Coupling Alignment: This must be checked before

and after system start-up; after 300 hours of opera-

tion; and again after 1200 hours of operation. Follow

procedure given in Item No. 6 of the INSTALLATION

Section. Again, we recommend strongly that a routine

preventative maintenance schedule be devised and

followed to achieve optimum life from the Pump.

REPAIRS

GUSHER 7600 SERIES TOP PULL-OUT PUMPS were

designed with today’s high cost of maintenance and re-

pairs in mind. They are basically constructed in three

(3) components: Chair or Barrel with Drive Motor, Sta-

tionary Element, and the Rotating Element. (We rec-

ommend that a spare Rotating Element be kept in your

Maintenance Stock Room.)

SECTION I CHAIR WITH DRIVE MO-

TOR: Removal and Replacement

1. Disconnect electrical leads. (During installation

it is advisable to allow sufﬁcient ﬂexible conduit

(approximately 4 feet) to allow removal without

disconnection of electrical leads.)

2. Disconnect Coupling (#32).

3 . Remove Nuts (#54) and Screws (#51). Not

shown.

4A. Chair and Motor can be removed from service.

13. Ball Bearing Installation:

a. Bearing installation should take place under

conditions of cleanliness consistent with the

precision of the product involved. All tables

and tools must be clean and free from dirt or

other foreign matter that could end up in the

bearing.

b. When a bearing is installed, the mount-

ing force should be applied against the

race which is being press-ﬁtted. A bearing

should never be forced onto a shaft by pres-

sure or hammer blows applied to outer ring,

nor should the bearing be press-ﬁtted into a

housing by force applied to the inner ring.

Ruthman Companies was co-founded in 1912 by brothers

Alois and Edward Ruthman as the “Ruthman Machinery

Company.” Based in Cincinnati, the company serviced the

steamboats that traveled the Ohio River.

brand, Gusher Pumps.

Alois’ son Thomas R. Ruthman joined the family business in 1949, growing the

business globally through organic growth and the acquisition of complementary

technologies. In the early 1990’s, Alois’ grandson, Thomas G. Ruthman, became

the third generation of Ruthmans in the pump business. Over the years, Ruth-

man Companies has expanded its product line from the original centrifugal coolant

pumps to include valves, vertical turbine pumps, positive displacement pumps, gear

pumps, and other specialized pump equipment, while upholding its reputation as a

leader in the custom engineering of pumps for the most challenging applications.
