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 8) and
the corresponding Parts Lists. Maintenance and
repair instructions for the engine is covered sepa
rately in the specific literature available from 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.
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

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.
