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.
