NAMEPLATE INFORMATION
On the casing of every Gusher pump is a nameplate that provides information about the pump’s
hydraulic characteristics. This information will be used when ordering spare or replacement parts for
your pump.
RECEIVING and INSPECTION
Gusher Pumps, Inc. has taken great care in
preparing your pump for shipment, however,
due to circumstances beyond our control, your
shipment may be received damaged. There-
fore, we strongly recommend that you take a
few minutes to check your pump upon receipt.
Check for cracked, bent, severely misaligned
(minor misalignments almost always occur
during shipment), or even missing parts. If any
such damage has occurred, you must report it
to the delivering carrier and Gusher Pumps, Inc.
immediately.
We also recommend that you check the model
number, horsepower, current characteristics,
and ft. head of pump received to ensure that you
have received the pump you ordered for your
specific operating conditions. If you should find
some discrepancy, report it to Gusher at once.
If your pump is not going to be installed within
six months, several precautions must be tak-
en;
1. Preservative treatment of bearings and ma-
chined surfaces is required.
2. Remove packing on pumps with packed
stuffing box, the stuffing box and shaft
sleeve must be oil lubricated to also protect
against moisture.
3. Units equipped with mechanical seals must
also be oil lubricated with an oil can through
the NPT port while rotating the shaft by
hand.
4. Pump suction and discharge ports must be
covered to prevent foreign material from
getting into the pump and causing damage
when pump is started at a later date.
5. Pump must be stored in a dry location.
6. Rotate pump shaft several times every other
month.

OPERATION & MAINTENANCE
• OPERATION
Before starting the pump the reservoir should
be filled to the minimum level so as to com-
pletely submerge the bottom pump impeller
housing in the liquid which assures priming of
the pump.
Upon initial start up we recommend that you
check and maintain the minimum liquid level
in your reservoir, it is also advisable to check
your piping for leaks at this time. We also rec-
ommend that you check and record the pump
discharge pressure, line voltage and amperage
being drawn by the motor and operating tem-
perature of the bearings. Temperature should
be checked with a pyrometer, do not check by
touch. Temperatures that are hot to the touch
are often well within the maximum operating
temperature of 225OF.
If a problem develops check the trouble shoot-
ing list on page 11. If you are unable to solve
your problem please feel free to contact the
factory.
• MAINTENANCE
Normally after proper installation and under
normal operating conditions (8 hours daily duty
in clean liquid with SG of 1) the pump requires
very little attention.
Before shipment all Gusher pumps have been
tested and greased at the plant, therefore lubri-
cation is not necessary for approximately six to
eight months. Remember, when lubricating ball
bearings that too much grease will cause bear-
ings to run hot, so grease bearings sparingly
when it is necessary. We recommend the use of
Chevron SRI #2 grease.
Because of the vast range of operating condi-
tions it is difficult to recommend one set sched-
ule for periodic maintenance. The more severe
the application the more attention the pump will
require. When a pump operates in a high tem-
perature application (over 1500F) it is recom-
mended to grease the ball bearings sparingly
once a month (approx. 1 gram). In hostile envi-
ronments where abrasives are present the pump
may need to be inspected for wear quarterly.
This should include inspection of the impellers,
bushings and seals. On hostile duty pumps the
lower bushing is constructed of Tungsten Car-
bide. This material is sensitive to thermal shock.
Use caution when rapidly changing the temper-
ature of the liquid. If the temperature change is
too rapid bushing failure will occur.

DISASSEMBLY PROCEDURE
1. Turn the pump over to where the intake flange
(#9) is up.
2. CAUTION! Before proceeding, be sure to mark
the impeller housing (#10) on the outside so
that you can put them back on in exactly the
same position that you take them off and also
number them so that you can put them back
on in exactly the same order that the came off.
3. Remove the intake flange retaining bolts (#5)
and remove the intake flange (#9).
4. Before continuing, you need to remember to
number the impellers (#8) so that you can put
them back on in exactly the same order that
you take them off of the shaft.
5. Remove the impeller retaining nut (#6) and
remove the impeller (#8). If the impeller is worn,
replace it.
6. Remove the impeller housing (#10). If the hous-
ing is worn, replace it.
7. Continue removing the impellers (#8) and the
impeller housings (#10) remembering to mark
impeller housings (#10) for position and the
order that they are in; also remember to mark
the impellers as far as order until you get to the
final impeller.
8. When you get to the last impeller, extreme care
should be taken in removing the last impeller
because the mechanical seal (#11) is directly
behind this impeller.
9. Remove the slinger retaining screws (#4) form
the slinger (#12) if applicable.
10. Remove the external fan cover (#22).
11. Remove the external fan (#21).
12. Remove the motor retaining bolts (#1).
13. Using a hammer and a straight screwdriver,
insert the screwdriver between the motor end
bell (#19) and the motor can (#18) and pry the
motor end bell (#19) off of the motor can (#18).
14. Remove the motor can (#18) from the motor can
adapter (#16) if applicable.
15. Once you have removed the motor can (#18)
then remove the motor can adapter bolts (#2)
and the motor can adapter (#16) if applicable to
your pump.
16. Remove the lower bearing retainer bolts. (#3).
17. The use of a hand press is recommended in
pressing the shaft (#17) out of the pump body
(#13). If a press is not available the following
steps will work. Using a hammer and a piece of
wood, hold the piece of wood on the shaft (#17)
over the threads and hit the wood with the ham-
mer so you won’t hurt the threads, and remove
the shaft from the pump body (#13).
18. Once you have removed the shaft, check the
bearings and replace if they show signs of wear.
FOR ASSEMBLY REVERSE
THE ABOVE PROCEDURE
In order to insure proper reassembly of your pump,
be sure to do the following things:
1. Check the seal. If it is worn, replace it.
2. When replacing the mechanical seal, make sure
the drive pin is in place, if applicable.
3. When pressing the seal (#11) into the pump
body (#13), press only on the outer metal edge.
4. When you press the seat of the seal (#11) on the
impeller (#8) use something that is non-metallic
so that it won’t damage the seal. Also, lubricate
the impeller (#8) before pressing the seal (#11)
onto the impeller hub.
5. When installing the impellers (#8) and the im-
peller housings (#10, they must go back onto
the shaft exactly the same way that they were
removed.
6. Once you have reassembled the pump and have
put the external fan (#21) back onto the shaft
(#17), rotate the pump shaft (#17) by hand to
make sure that the pump turns freely and is not
in a bind.

Ruthman...
Another Word for Innovation
It began in 1913, servicing
mechanical components of
the steamboats on the Ohio
River. The company founder,
Alois Ruthman, was a man
of vision and saw part of the
future of the company was
in the development of a reli-
able industrial pump.
In 1924, with the conception of the first vertical ball
bearing sealless centrifugal pump, Ruthman Pump
and Engineering furthered the design on a unit with a
one piece motor driven shaft. The pump was called
“Gusher”, giving birth to the trade name Gusher
Pumps, and the coining of the term “coolant pump”.
Wanting to carry on the tradition of quality and reli-
ability started by his father, Thomas R. Ruthman
joined the company in 1949. In the early 1990’s
Thomas R. Ruthman’s son, Thomas G. Ruthman
joined the company, continuing this same tradition.
Maintaining the reputation of Gusher Pumps by in-
novation and customer service, the company has
grown to service companies worldwide.
