MAINTENANCE AND REPAIR
Review all SAFETY information in Section A.
Gorman‐Rupp Diaphragm Primers require little
service due to their rugged, minimum‐mainte
nance design. However, if it becomes necessary to
replace parts, follow these instructions which are
keyed to the sectional view (Figure 1) and the ac
companying parts lists.
Use
Only Genuine Gorman-Rupp
re
placement parts. Failure to do so may cre
ate a hazard and damage the diaphragm
primer or diminish optimal diaphragm
primer performance. Any such hazard,
damage or diminished performance is not
covered by the warranty.
NOTE
When appropriate recycling facilities are available,
the user should recycle components and fluids
when doing any routine maintenance / repairs and
also at the end of the pump’s useful life. All other
components and fluids shall be disposed of ac
cording to all applicable codes and regulations.
This manual will alert personnel to
known procedures which require spe
cial attention, to those which could
damage equipment, and to those which
could be dangerous to personnel.
How
ever, this manual cannot possibly antici
pate and provide detailed instructions
and precautions for every situation that
might occur during maintenance of the
unit. Therefore, it is the responsibility of
the owner/maintenance personnel to
ensure that only safe, established main
tenance procedures are used, and that
any procedures not addressed in this
manual are performed only after estab
lishing that neither personal safety nor
pump integrity are compromised by
such practices.
Before attempting to service the Di
aphragm Primer:
1. Familiarize yourself with this man
ual.
2. Shut down the engine and discon
nect the positive battery cable, or
lock out incoming power to the mo
tor and take precautions to ensure
that the pump will remain inopera
tive.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature and make
sure the pump is cool before open
ing any covers, plates, or plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau
tiously.
7. Drain the pump.
Death or serious personal injury and
damage to the diaphragm primer pump
or components can occur if proper lift
ing procedures are not observed. Make
certain that hoists, chains, slings or
cables are in good working condition
and of sufficient capacity and that they
are positioned so that loads will be bal
anced and the diaphragm primer or
components will not be damaged when
lifting. Suction and discharge hoses
must be removed from the diaphragm
primer before lifting. Lift the diaphragm
primer or component only as high as ne
cessary and keep personnel away from
suspended objects.
