INTRODUCTION

INTRODUCTION

Thank You for purchasing a Gorman-Rupp Self-
Priming Centrifugal Pump. Read this manual
carefully to learn how to safely install and operate
yourpump. Failure todoso could resultinpersonal
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 pumps. 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.
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:
