SAFETY - SECTION A
This information applies to Super U Se­
ries 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 before
opening 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 highly
corrosive and abrasive industrial waste
materials and residues containing spe­
cified entrained solids. Do not attempt
to pump volatile, explosive or flam­
mable liquids which may damage the
pump or endanger personnel as a result
of pump failure.
After the pump has been positioned,
make certain that the pump and all pip­
ing connections are tight, properly sup­
ported and secure before operation.
Do not operate the pump without the
guards in place over the rotating parts.
Exposed rotating parts can catch cloth­
ing, fingers, or tools, causing severe in­
jury to personnel.
Do not remove plates, covers, gauges,
pipe plugs, or fittings from an over­
heated pump. Vapor pressure within the
pump can cause parts being disen­
gaged to be ejected with great force. Al­
low the pump to cool before servicing.
Do not operate the pump against a
closed discharge valve for long periods
of time. If operated against a closed dis­
charge valve, pump components will
deteriorate, and the liquid could come
to a boil, build pressure, and cause the
pump casing to rupture or explode.
