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.
This Installation, Operation, and Maintenance
manual is designed to help you achieve the best
performance and longest life from your Gorman‐
Rupp pump.
This pump is an 80 Series, semi‐open impeller, self‐
priming centrifugal model with a suction check
valve. The pump is designed for straight‐in suction
where the medium being pumped enters directly
into the impeller eye. It is designed for handling
most non‐volatile, non‐flammable liquids contain
ing specified entrained solids. The basic material
of construction for wetted parts is gray iron. The
pump may be approved or modified for handling
volatile, flammable liquids only by the Gorman‐
Rupp Company or an authorized distributor.
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:
