NOTICE
The above safety instruction tags were permanently affixed to your pump prior
to shipment. Do not remove, paint over or obscure in any manner.
Failure to heed these warnings could result in serious bodily injury to the
personnel operating and maintaining this equipment.
SAFETY PRECAUTIONS FOR LIQUID RING PUMPS
Please read the following safety information on this page before operating your vacuum pump.
•
Do not operate the pump without the coupling and belt guard properly attached. Disconnect the pump motor from
the electrical supply at the main disconnect before removing the belt guard. Replace the belt guard before
reconnecting the power supply to the pump motor. Operating the pump without the belt guard properly installed
exposes personnel in the vicinity of the pump to risk from rotating drive components.
CAUTION: Do not operate the pump with oxygen-enriched gas in the suction line,
unless the pump has been
properly cleaned, inspected and certified to be free of hydrocarbon presence and prepared with an inert fluid
suitable for the application.
Oxygen-enriched gas is defined as gas of which the constituents include by volume (mol. %) an amount of oxygen
greater than that of standard atmospheric air (typically 20-21% by volume).
If the oxygen content in the gas stream exceeds the proportions found in standard atmospheric air, then it is
considered an oxygen-enriched gas and standard mineral oil, synthetic hydrocarbon oil or other non-inert fluids
should not be used.
WARNING: Pumping oxygen-enriched gases with mineral oil, synthetic hydrocarbon oil or other non-inert
fluids can cause fire or explosion in the pump, resulting in damage or serious bodily injury or death.
•
Take precautions to avoid prolonged or excessive exposure to oil mist or process materials emanating from the
discharge of the pump.
•
Do not allow the pump to discharge into a closed, or inadequately ventilated room. Always use a discharge oil mist
eliminator unless the pump discharge is discharged to outside atmosphere. Laws and ordinances may pertain to
your local area regarding discharge of oil mist or vapor to atmosphere. Check local laws and ordinances prior to
operation of the pump with discharge to outside atmosphere. Venting of the discharge of an oil mist eliminator to
outside atmosphere is highly recommended.
•
Do not restrict the pump discharge in any way, or place valves in the discharge line. The vacuum pump is a
compressor and will generate high pressures without stalling the motor when operated at low suction pressures.
Excessive pressure could cause pump damage or serious bodily injury.
•
Disconnect the pump motor from the electrical supply at the main disconnect before disassembling or servicing
the pump. Make sure pump is completely reassembled, the belt guard is properly installed, and that all fill and
drain valves are installed and closed before reconnecting the power supply.
Accidental starting or operation of
the pump while maintenance is in progress could cause pump damage or serious bodily injury.
•
Lift pump only by the lifting lugs supplied with the pump. DO NOT lift equipment attached to pump by the pump
lifting lugs.
•
Do not touch hot surfaces on the pump. In normal operation at low pressures, surface temperatures will not
normally exceed 180° F (82° C). Prolonged operation at 200 Torr (267 mbar a) may cause surface temperatures as
high as 220° F (104° C)
