SAFETY ‐ SECTION A
This information applies to 50 Series ba­
sic pumps. Gorman‐Rupp has no con­
trol over or particular knowledge of the
power source which will be used. Refer
to the manual accompanying the power
source before attempting to begin
operation.
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 pro­
vide detailed instructions and precau­
tions for each specific application or for
every situation that might occur during
maintenance of the unit. Therefore, it is
the responsibility of the owner, installer
and/or maintenance personnel to en­
sure that applications and/or mainte­
nance procedures not addressed in this
manual are performed only after estab­
lishing that neither personal safety nor
pump integrity are compromised by
such applications or procedures.
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 clear
liquids. Do not attempt to pump volatile,
corrosive, or flammable materials which
may damage the pump or endanger per­
sonnel 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. Suction and dis­
charge hoses and piping must be re­
moved from the pump before lifting.
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 operate the pump against a
closed discharge valve for long periods
of time. If operated against a closed dis­
