INTRODUCTION

INTRODUCTION

Thank You

 for purchasing a Gorman‐Rupp 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.

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 or
its application  which  are not covered in this man­
ual or in other literature accompanying this unit,
please contact your Gorman‐Rupp distributor, or
The Gorman‐Rupp Company:
