INTRODUCTION
INTRODUCTION
Thank You
for purchasing a Gorman‐Rupp RS or
RD Roto‐Prime
Series 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.
A set of three manuals accompanies your pump.
Each set consists of three parts; the Installation/
Operation Manual contains essential information
on installing and operating the pump. However,
since pump installations are seldom identical,
some of the information only summarizes general
recommendations and practices required to in
spect, position, and arrange the pump and piping.
The Parts List Manual provides performance
curve(s), a pump model cross‐section drawing,
and parts list for your pump.
The Maintenance and Repair Manual provides
troubleshooting and maintenance instructions re
quired to properly diagnose operational problems,
and to service the pump components. Contact the
factory for the authorized repair facility closest to
you.
This pump is a Roto‐Prime
self‐priming centrifu
gal petroleum pump, designed to handle
petro
leum products only
. It incorporates an integral va
riable‐capacity vane pump which automatically
evacuates air and vapor from the suction line. This
pump should
not
be used to handle water or other
non‐petroleum liquids. For specific service, con
tact your Gorman‐Rupp distributor or the Gorman‐
Rupp Company.
The basic pump is not furnished with a mounting
base and power source; however, these items are
available from the factory as optional equipment.
The pump is designed to be driven by an explo
sion‐proof motor with a maximum full load speed
of either 1750 RPM (RS Series) or 3450 RPM (RD
Series).
Because pump installations are seldom identical,
this manual cannot possibly provide detailed in
structions and precautions for every aspect of
each specific application. Therefore, it is the re
sponsibility of the owner/installer of the pump to
ensure that applications not addressed in this
manual are performed
only
after establishing that
neither operator safety nor pump integrity are com
promised by the installation. Pumps and related
equipment
must
be installed and operated ac
cording to all national, local and industry stan
dards.
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‐
Rupp Company:
