PAGE B - 2 INSTALLATION
If the maximum shelf life has been exceeded, or if
anything appears to be abnormal, contact your
Gorman‐Rupp distributor or the factory to deter­
mine the repair or updating policy. Do not put the
pump into service until appropriate action has
been taken.
POSITIONING PUMP
Lifting
Use lifting equipment with a capacity of at least 5
times the weight of the pump, including the
weight of options and customer installed
accessories. Customer installed equipment such
as suction and discharge piping and fittings must
be removed before attempting to lift the pump.
The pump assembly can be seriously
damaged if the cables or chains used to lift
and move the unit are improperly wrapped
around the pump.
For the approximate weight of your pump, refer to
the pump specification data sheet or contact your
Gorman‐Rupp distributor or the Gorman‐Rupp
Company.
Mounting
Locate the pump in an accessible place as close as
practical to the liquid being pumped. Level mount­
ing is essential for proper operation.
The pump may have to be supported or shimmed
to provide for level operation or to eliminate vibra­
tion.
When the pump is installed under unusual
conditions, the priming tube(s) may vi­
brate abnormally. If this occurs after the
pump and piping are properly secured,
contact the factory to obtain optional
springs for the priming pump group grind.
If the vibration is not corrected, the tubing
could fatigue and rupture, spilling the liq­
uid being pumped and resulting in a fire
hazard.
GROUNDING
To eliminate electrostatic build‐up by the liquid be­
ing pumped, it is recommended that the pump be
grounded by attaching a ground wire assembly to
a ground rod. Install the ground rod in accordance
with the National Electrical Code and all local
codes. Be sure the clamp or fastener has made a
tight electrical connection with the rod.
Inspect and test the ground wire assembly
for conductivity. Replace broken or frayed
wire before resuming operation.
SUCTION AND DISCHARGE PIPING
Damage to the pump resulting from debris
in the suction line will not be covered by the
pump warranty. Before connecting the
suction and discharge piping, carefully
check the storage tank and piping for con­
struction debris such as nuts, bolts, wire,
weld slag, and other foreign material. In­
stall a commercially available 80 mesh
screen and a filter in the suction line to pre­
vent debris from entering the pump.
Pump performance is adversely effected by in­
creased suction lift, discharge elevation, and fric­
tion losses. See the performance curve and oper­
ating range shown in the Parts List manual to be
sure your overall application allows the pump to
operate within the safe operation range.
