INTRODUCTION
INTRODUCTION
This manual contains installation, operation, and
maintenance instructions for the Gorman‐Rupp
GRP33-08A and GRP33-08B Air Release Valves
and corresponding GRP52 Air Release Valve In
stallation Kits.
Read this manual
carefully to learn
how to safely install and maintain your Air Release
Valve. Failure to do so could result in personal in
jury or damage to the pump.
The Air Release Valves are designed to work in
conjunction with the integral priming pump and
priming tubes installed between the valve, priming
pump and the pump suction. Air or vapor expelled
by the priming pump during initial priming or
re‐priming is directed through the Air Release
Valve, thereby permitting the priming pump to
prime the centrifugal pump against relatively high
discharge heads.
If there are any questions regarding the pump or
Air Release Valve application which are not cov
ered in this manual or in other literature accompa
nying this unit, please contact your Gorman‐Rupp
distributor, or The Gorman‐Rupp Company:
