Lifting
Use lifting and moving equipment with a capacity
of at least 5 times the weight of the pump, not in-
cluding the weight of any customer installed ac-
cessories. Customer-installed equipment such as
discharge piping must be removed before at-
tempting to lift. Refer to the Pump Specification
Data Sheet or contact the Gorman-Rupp Company
for the approximate weight of your pump.
Do not attempt to lift the pump by the hy-
draulic hoses or the piping. Attach proper
lifting equipment to the lifting device fitted
to the pump. If chains or cable are
wrapped around the pump to lift it, make
certain that they are positioned so as not to
damage the pump, and so that the load will
be balanced.
Hydraulic Power Source Connections
The hydraulic connections on the hoses supplied
with the pump are male and female. The threads
on these hoses must be kept clean and protected.
Be sure hydraulic hoses and connections are
clean before making connections at the pump and
power source. Check connections to be sure they
are tight before starting the power source.
Make sure hydraulic hose connections
are fully tightened. Hydraulic hoses are
equipped with check valves in each end.
Hose connections must be tight to fully
open these check valves. Failure to tighten
connections can cause excessive hydrau-
lic pressure, resulting in damage to the hy-
draulic motor and/or other components.
Rotation
Before putting the pump into service, check pump
rotation.
While checking impeller rotation, secure
the pump to prevent rolling.
Suspend the pump by the lifting handle. Quickly
apply power and note the direction of pump kick-
back. As viewed from the top, the pump should
kickback in a counterclockwise direction (see
Figure 2); this will indicate that impeller rotation is
correct.
If the pump kicks back in a clockwise direction, im-
peller rotation is incorrect. Consult the Mainte-
nance and Repair manual and make sure pres-
sure is supplied to correct port of the hydraulic mo-
tor. Recheck pump kickback; it should now be in a
counterclockwise direction.
