PUMP AND SEAL DISASSEMBLY
AND REASSEMBLY
Review all SAFETY information in Section A.
Follow the instructions on all tags, label and de-
cals attached to the pump.
This pump requires little service due to its rugged,
minimum-maintenance design. However, if it be-
comes necessary to inspect or replace the wearing
parts, follow these instructions which are keyed to
the Sectional Views (see Figures 1 through and 8)
and the corresponding Parts Lists. Maintenance
and repair instructions for the engine is covered
separately in the specific literature supplied by the
manufacturer.
Many pump service functions may be performed
without separating the pump end assembly from
the engine. However, the priming chamber assem-
bly (3, Figure 3) and discharge check valve assem-
bly (2, Figure 3) must be removed to service most
pump components. The following instructions as-
sume complete disassembly of the pump is re-
quired.
Before attempting to service the pump, shut down
the engine and take precautions to ensure that it
will remain inoperative. Close all valves in the suc-
tion and discharge lines and drain the pump cas-
ing by removing the casing drain plug (13, Figure
4). Clean and reinstall the drain plug.
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 open or service the
pump:
1. Familiarize yourself with this man-
ual.
2. Shut down the engine, disconnect
the positive battery cable and take
precautions to ensure that the
pump will remain inoperative.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature and make
sure it is cool before opening any
covers, plates, gauges, or plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau-
tiously.
7. Drain the pump.
This pump is designed to handle materi-
al which could cause illness through di-
rect exposure or emitted fumes. Wear
adequate protective clothing when
working on the pump or piping.
Use only replacement parts provided or
approved by Gorman-Rupp. Use of non-
authorized parts may result in damage to
the equipment and/or injury to personnel
and will invalidate the warranty.
