PIPING
The pump volute is equipped with a standard
1−1/2−inch NPT tapped discharge connection.
Either hose or rigid pipe may be used for the dis-
charge connection.
For maximum pumping capacity, use non-collaps-
ible hose or rigid piping, and keep the discharge as
short and straight as possible. If rigid piping is
used, minimize the use of elbows and fittings which
increase friction losses and reduce pump perform-
ance.
A check valve or throttling valve may be installed in
the discharge line to control siphoning or back flow
when the pump is shut off.
PUMP POWER CABLE CONNECTIONS
The pump is provided with two 30-foot (3 m) power
cables. Splicing of the power cables is not recom-
mended by the Gorman-Rupp Company due to
safety and warranty considerations.
Never attempt to alter the length or re-
pair any power cable with a splice. The
pump motor and cable must be com-
pletely waterproof. Damage to the pump
or personal injury may result from alter-
ations.
When connecting the pump power cables to the
vehicle, first check the vehicle owner’s manual to
determine if the vehicle has a negative or a positive
grounding system.
Always make sure the switch on the
power cables is in the OFF position be-
fore connecting the leads to the vehicle
battery. Failure to do so could cause
arcing, resulting in explosion or fire.
Refer to Figure 3 for pump power cable connec-
tions, and proceed as follows:
