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.
If this pump is used with volatile and/or
flammable liquids, overheating may
produce dangerous fumes. Take pre
cautions to ensure the area surrounding
the pump is adequately ventilated. Al
low the pump to cool and use extreme
caution when venting the pump, or
when removing covers, plates, plugs, or
fitting.
Overheated pumps can cause severe
burns and injuries. If overheating of the
pump occurs:
1. Stop the pump immediately.
2. Ventilate the area.
3. Allow the pump to completely cool.
4. Check the temperature before
opening any covers, plates,
gauges, or plugs.
5. Vent the pump slowly and cau
tiously.
6. Refer to instructions in this manual
before restarting the pump.
After the vehicle is positioned for pump
maintenance, block the wheels and set
the emergency brake before attempting
to disconnect the drive shaft or remove
the pump. Be sure the pump is properly
reinstalled and secure before opera
tion.
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 completely cool before
servicing.
The gearbox provided on this pump is
designed for operation at 1000 RPM
maximum input speed. If operated at a
higher RPM, pump components may be
destroyed.
Never run this pump backwards. Be cer
tain that rotation is correct before fully
engaging the pump.
Never run the pump dry of pumping me
dium. There must be a supply of liquid to
the pump at all times to prevent destruction
of the shaft seal faces.
Pumps and related equipment must be in
stalled and operated according to all na
tional, local and industry standards.
