INTRODUCTION
Thank You for purchasing a Gorman‐Rupp SF
Series explosion‐proof pump. Read this manual
carefully to learn how to safely install and operate
your pump. Failure to do so could result in personal
injury or damage to the pump.
This manual contains essential information on in­
stalling and operating the pump, and on making
electrical connections. However, since pump in­
stallations are seldom identical, some of the infor­
mation only summarizes general recommenda­
tions and practices required to inspect, position,
and arrange the pump and piping.
This manual provides troubleshooting and mainte­
nance instructions required to properly diagnose
operational problems, and to service the pump hy­
draulic components only. Pump motor mainte­
nance may be performed only by a Gorman‐Rupp
authorized repair facility, or the factory. Otherwise,
the pump warranty will be negated, and damage
to the pump, and injury or death to personnel can
result. Contact the factory for the authorized repair
facility closest to you.
The motor powering this pump is approved by
either CSA and/or FM for Class 1, Division 1,
Groups C and D environments. Refer to the name­
plate on your pump for agency approval informa­
tion. All repairs to the pump, other than seal, impel­
ler and other hydraulic components, must be per­
formed by a Gorman‐Rupp authorized repair facil­
ity or the factory. Any repairs to the motor assembly
performed by the customer or an unauthorized re­
pair facility negates the agency approval and the
motor warranty, and damage to the pump, and in­
jury or death to personnel can result. If the motor
is dual‐voltage, the pump is shipped from the fac­
tory wired only for the voltage shown on the name­
plate. If desired to have the voltage changed, re­
turn the pump to the factory or to a Gorman‐Rupp
authorized repair facility.
The pump motor must be operated through an ap­
propriate control box matching the voltage and
other characteristics of the motor. The control box
must provide for proper operation of the motor pro­
tection devices, such as the integral moisture and
thermal switches. Control boxes and other control
devices not integral to the pump are not covered
in this manual.
Pump construction is cast iron, with stainless steel
shaft and hardware.
These pumps may be equipped with a guide shoe
for mounting on guide rails in a wet well. A guide
rail system, controls and liquid level devices are
available from the factory as optional equipment.
If there are any questions regarding the pump
which are not covered in this manual or in other lit­
erature accompanying the unit, please contact
your Gorman‐Rupp distributor or the Gorman‐
