SAFETY - SECTION A
This information applies to 10 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 oper-
ation.
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 corro-
sive liquids containing specified en-
trained solids, residues and slurries. Do
not attempt to pump volatile or flam-
mable liquids which may damage the
pump or endanger personnel as a result
of pump failure.
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 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.
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.
This pump is designed to pump materi-
als which could cause serious illness or
injury through direct exposure or
emitted fumes. Wear protective cloth-
ing, such as rubber gloves, face mask,
and rubber apron, as necessary before
disassembling the pump or piping.
