SAFETY PRECAUTIONS FOR
ROTARY PISTON PUMPS
Please read the following safety information before
operating the vacuum pump.
• Do not operate the pump without the 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.
• Do not operate the pump with oxygen-enriched
gas (greater than 20% by volume) in the suction
line, unless the pump has been prepared with an
inert fluid suitable for the application.
WARNING !
Pumping oxygen-enriched gases with mineral
oil or other non-inert fluids can cause fire or
explosion in the pump, resulting in damage or
serious bodily injury.
• 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 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 the pump is completely reassembled, the
belt guard is properly installed, and 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 damage
or serious bodily injury.
• Lift pump only by the lifting lugs supplied with
the pump. Never 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).
