INTRODUCTION
INTRODUCTION
Thank You
for purchasing a Gorman-Rupp Prime-
Aire
r
Series priming-assisted pump.
Read this
manual
carefully to learn how to safely maintain
and service your pump. Failure to do so could re-
sult in personal injury or damage to the pump.
A set of three manuals accompanies your pump.
The Installation/Operation Manual contains essen-
tial information on installing and operating the
pump, and on making electrical connections. The
Parts List Manual provides performance curve(s),
a pump model cross-section drawing, and parts
list for your pump.
This Maintenance and Repair Manual provides
troubleshooting instructions required to properly
diagnose operational problems. Maintenance in-
structions within this manual are limited to the
pump hydraulic and drive components only. For
maintenance and repair of the engine or air com-
pressor, consult the separate literature provided by
the manufacturers.
This manual covers high head PA Series priming-
assisted models, which incorporate a 60 Series
straight centrifugal pump end. The pump is de-
signed for high pressure distribution of non-vola-
tile, non-flammable liquids that do not contain
large entrained solids. For specific service, contact
your Gorman-Rupp distributor or the Gorman-
Rupp Company.
As described on the following page, this manual
will alert personnel to known procedures which re-
quire special attention, to those which could dam-
age equipment, and to those which could be dan-
gerous to personnel. However, this manual cannot
possibly anticipate and provide detailed precau-
tions for every situation that might occur during
maintenance of the unit. Therefore, it is the respon-
sibility of the owner/maintenance personnel to en-
sure that
only
safe, established maintenance pro-
cedures are used, and that any procedures not ad-
dressed in this manual are performed
only
after es-
tablishing that neither personal safety nor pump in-
tegrity are compromised by such practices.
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:
