Series basic pumps. Gorman‐Rupp has
no control over or particular knowledge
of the power source which will be used.
Refer to the manual accompanying the
power source before attempting to be­
gin operation.
Because pump installations are seldom
identical, this manual cannot possibly
provide detailed instructions and pre­
cautions for each specific application.
Therefore, it is the owner/installer's re­
sponsibility to ensure that applications
not addressed in this manual are per­
formed only after establishing that nei­
ther operator safety nor pump integrity
are compromised by the installation.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man­
ual.
2. Disconnect or lock out the power
source to ensure that the pump will
remain inoperative.
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.
This pump is designed to handle most
non‐volatile, non‐flammable liquids
containing specified entrained solids.
Do not attempt to pump volatile, corro­
sive, or flammable liquids which may
damage the pump or endanger person­
nel as a result of pump failure.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam­
age to equipment. Attach lifting equip­
ment to the lifting device fitted to the
pump. If chains or cable are wrapped
around the pump to lift it, make certain
that they are positioned so as not to
damage the pump, and so that the load
will be balanced. The bail is intended for
use in lifting the pump assembly only.
Suction and discharge hoses and pip­
ing must be removed from the pump be­
fore lifting.
After the pump has been installed, make
certain that the pump and all piping or
hose connections are tight, properly
supported and secure before operation.
Do not operate the pump against a
closed discharge valve. If operated
against a closed discharge valve, pump
components will deteriorate, and the
liquid could come to a boil, build pres­
sure, and cause the pump casing to rup­
ture or explode. Momentary closure of a
discharge valve is acceptable only
when required for startup or shutdown
procedures.
Do not operate the pump without the
