PUMP OPERATION
This pump is designed to handle most
non-volatile, non-flammable liquids en-
countered in mine dewatering. Do not
attempt to pump volatile, explosive, or
flammable materials, or any liquids
which may damage the pump or endan-
ger personnel as a result of pump fail-
ure.
Liquid Temperature And Overheating
The maximum liquid temperature for the pump is
120
_ F (49_ C). Do not apply the pump at higher
operating temperatures.
Approach the pump cautiously after it
has been running. Although the motor is
cooled by the liquid being pumped, nor-
mal operating temperatures can be high
enough to cause burns. The tempera-
ture will be especially high if operated
against a closed discharge valve. Never
operate against a closed discharge
valve for long periods of time.
If overheating does occur, stop the pump immedi-
ately and allow it to cool before servicing it. Ap-
proach any overheated pump cautiously.
