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.
Allow an overheated pump to cool be-
fore servicing. Do not remove plates,
covers, gauges, pipe plugs, or fittings
from an overheated pump. Liquid within
the pump can reach boiling tempera-
tures, and vapor pressure within the
pump can cause parts being disen-
gaged to be ejected with great force. Af-
ter the pump cools, drain the liquid from
the pump be removing the casing drain
plug. Use caution when removing the
plug to prevent injury to personnel from
hot liquid.
Never run this pump backwards. Be cer-
tain that rotation is correct before fully
engaging 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.
Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded. Limit the maximum input
speed and operation range as indicated
on the performance curves on Page E-1.
The gearbox provided on this pump is
designed for operation at 2250 RPM
maximum input speed. If operated at a
higher RPM, pump components may be
destroyed.
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.
