INSTALLATION − SECTION B
Review all SAFETY information in Section A.
This section is intended only to summarize recom-
mended installation practices for the pump. If there
are any questions concerning your specific appli-
cation, contact your Gorman-Rupp distributor or
the Gorman-Rupp Company.
PREINSTALLATION INSPECTION
The pump was inspected and tested before ship-
ment. Before installation, inspect the pump for
damage which may have occurred during ship-
ment. Check as follows:
a. Inspect the pump assembly for cracks, dents,
damaged threads on the hydraulic connect-
ing hoses, and other obvious damage.
b. Check for and tighten loose attaching hard-
ware. Since gaskets tend to shrink after dry-
ing, check for loose hardware at mating sur-
faces.
c. If the pump was shipped with hydraulic
hoses, inspect the hoses for cuts or damage
to the threaded ends.
d. Check the pump hydraulic motor for any oil
leaks, and tighten any hardware as required.
e. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties
as indicated.
f. Check that the hydraulic power source pro-
vides the required horsepower and flow to
properly and safely operate the pump (see
Table 1).
If anything on the pump appears to be abnormal,
contact your Gorman-Rupp distributor or the fac-
tory to determine the repair or updating policy. Do
not put the pump into service until appropriate ac-
tion has been taken.
Lubrication
The pump was fully lubricated when shipped from
the factory. However, always check the lubricant
level before installing the pump (see LUBRICA-
TION in MAINTENANCE AND REPAIR).
PUMP INSTALLATION
Pump and Power Source Specifications
The Gorman-Rupp Company manufactures a hy-
draulic power unit specifically designed to power
the hydraulic pump. Only open-center valves
may be used in a customer-supplied power
source, with flows and pressures not exceeding
the nominal specifications shown for your pump in
Table 1. Do not use closed-center valves, or op-
erate the pump at higher flows or pressures.
Closed-center valves or operation at higher flows
or pressures will damage the pump motor and/or
seal, and void the pump warranty.
Do not use closed-center valves. Return
flow from the hydraulic motor must be
allowed to return directly to the oil reser-
voir to enable the pump impeller to
gradually slow to a stop. Closed-center
valves will block this flow, causing dam-
age to the hydraulic motor and/or the
pump seal.
See Figure 1 for a typical hydraulic schematic for a
customer-supplied power source. Consult the fac-
tory for additional information concerning the ap-
propriate hydraulic power source.
