INTRODUCTION
INTRODUCTION
Thank You
for purchasing a Gorman‐Rupp SFV/
SFEV 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
no
t 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
