INSTALLATION - SECTION B
GENERAL INFORMATION
Review all SAFETY information in Section A.
Since pump installations are seldom identical, this
section is intended only to summarize general rec­
ommendations and practices required to inspect,
position, and arrange the pump and piping. If there
are any questions concerning your specific instal­
lation, contact your Gorman‐Rupp distributor or
the Gorman‐Rupp Company.
This pump is not designed to handle water.
Operation of the pump with water or water‐
based solutions will damage the group
grind within the vane‐type priming pump.
Do not connect this pump to a storage
tank which has been filled with water until
the tank and lines have been completely
drained and flushed. Install a commercially
available 80 mesh screen and a filter in the
suction line to prevent debris from entering
the pump. Check pump rotation with the
suction line disconnected.
Most of the information pertains to a standard stat­
ic lift application, where the pump is positioned
above the free level of the liquid to be pumped.
If installed in a flooded suction application,
where the liquid is supplied to the pump under
pressure, some of the information such as mount­
ing, line configuration, and priming must be tai­
lored to the specific application. Since the pres­
sure supplied to the pump is critical to perform­
ance and safety, be sure to limit the incoming pres­
sure to 50% of the maximum permissible operating
pressure shown on the pump performance curve.
For further assistance, contact your Gorman‐Rupp
distributor or the Gorman‐Rupp Company.
PUMP DIMENSIONS
For the approximate physical dimensions of your
pump, refer to the pump specification data sheet or
contact your Gorman‐Rupp distributor or the Gor­
man‐Rupp Company.
PREINSTALLATION INSPECTION
The pump assembly was inspected and tested be­
fore shipment from the factory. Before installation,
inspect the pump for damage which may have oc­
curred during shipment. Check as follows:
a. Inspect the pump for cracks, dents, damaged
threads, 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. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties
indicated. Note the direction of rotation indi­
cated on the pump. Check that the pump
shaft rotates in the required direction.
Only operate this pump in the direction in­
dicated on the pump body and/or the ac­
companying decal. Reverse rotation of the
shaft will adversely effect pump perform­
ance, and the pump could be seriously
damaged.
d. Check levels and lubricate as necessary. Re­
fer to LUBRICATION in the MAINTENANCE
AND REPAIR section of this manual and per­
form duties as instructed.
e. If the pump and power source have been
stored for more than 12 months, some of the
components or lubricants may have ex­
ceeded their maximum shelf life. These must
be inspected or replaced to ensure maxi­
mum pump service.
