OPERATION - SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, labels and
decals attached to the pump.
This pump is designed to handle sew­
age containing large entrained solids
and corrosives. Do not attempt to pump
volatile, corrosive, or flammable liquids
which may damage the pump or endan­
ger personnel as a result of pump fail­
ure.
Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded. The maximum continuous
operating speed for this pump is 2400
RPM.
PRIMING
Install the pump and piping as described in IN­
STALLATION. Make sure that the piping connec­
tions are tight, and that the pump is securely
mounted. Check that the pump is properly lubri­
cated (see LUBRICATION in MAINTENANCE
AND REPAIR).
This pump is self‐priming, but the pump should
never be operated unless there is liquid in the
pump casing.
Never operate this pump unless there is
liquid in the pump casing. The pump will
not prime when dry. Extended operation of
a dry pump will destroy the seal assembly.
Add liquid to the pump casing when:
1. The pump is being put into service for the
first time.
2. The pump has not been used for a consider­
able length of time.
3. The liquid in the pump casing has evapo­
rated.
Once the pump casing has been filled, the pump
will prime and reprime as necessary.
After filling the pump casing, reinstall
and tighten the fill plug. Do not attempt
to operate the pump unless all connect­
ing piping is securely installed. Other­
wise, liquid in the pump forced out un­
der pressure could cause injury to per­
sonnel.
To fill the pump, remove the pump casing fill cover
or fill plug in the top of the casing, and add clean
liquid until the casing is filled. Replace the fill cover
or fill plug before operating the pump.
STARTING
Consult the operations manual furnished with the
engine.
OPERATION
Either a Gorman‐Rupp automatic air release valve
or a hand operated shutoff valve may be installed in
a bypass line.
Lines With a Bypass
If a Gorman‐Rupp Automatic Air Release Valve has
been installed, the valve will automatically open to
allow the pump to prime, and automatically close
after priming is complete (see INSTALLATION for
Air Release Valve operation).
If the bypass line is open, air from the suction line
will be discharged through the bypass line back to
