INTRODUCTION
This Installation, Operation, and Maintenance
Manual is designed to help you achieve the best
performance and longest life from your Gorman‐
Rupp J Series submersible pump.
The manual applies
only
to the submersible pump
model listed on the cover and in
MAINTENANCE
AND REPAIR - SECTION E
.
This J Series pump is driven by a waterproof sub
mersible electric motor. The pump motor
must
be
operated through an appropriate control box
matching the voltage and other characteristics of
the motor. The control box must also provide for
proper operation of the motor protection devices
such as the integral moisture and thermal
switches. Control boxes and other control devices
other than those integral to the pump motor are
no
t
covered in this manual. Refer to other literature ac
companying the pump.
Pump construction is cast iron, with stainless steel
shaft and hardware. This pump will handle solids
up to 5.7 inches (145 mm) in diameter.
This pump is equipped with a cooling jacket, which
does not require an outside source of cooling wa
ter; liquid being pumped is forced through a nar
row opening behind the impeller and circulated
through the cooling jacket. The pump is designed
to operate in a fixed piping system in a dry pit. Be
cause of its waterproof integrety, the pump will
continue to operate if the dry pit becomes flooded.
If there are any questions regarding the pump or
motor which are not covered in this manual or in
other literature accompanying this unit, please
