SAFETY PRECAUTIONS FOR
ROTARY PISTON PUMPS
Please read the following safety information before
operating the vacuum pump.
• Do not operate the pump without the beltguard
properly attached.
• Disconnect the pump from the electrical supply
at the main disconnect before removing the
beltguard. Replace the beltguard before
reconnecting the power supply. Operating the
pump without the beltguard secured in place
exposes people in the vicinity of the pump to risk
from rotating drive parts.
• Do not operate the pump with oxygen-enriched
gas in the suction line, where the proportion
of oxygen exceeds 21%, unless the pump has
been prepared with an inert uid suitable for the
application. Pumping oxygen-enriched gases
with mineral oil or other non-inert uids can
cause an explosion in the pump, resulting in
damage or injury.
• Take precautions to avoid prolonged or
excessive exposure to oil mist or process
materials from the discharge of the pump. Do
not allow the pump to discharge into a closed
room or a room without adequate ventilation.
Always use a discharge oil mist eliminator
unless the pump discharge is vented to the open
air. Venting the outlet of the oil mist eliminator to
the open air is highly recommended.
• Do not restrict the pump discharge line in any
way or place any valves in the discharge line.
The vacuum pump is a compressor and will
generate high pressures without the motor
stalling when operated at low suction pressures.
Excessive pressure buildup could cause
damage or injury.
• Disconnect the pump from the electrical supply
at the main disconnect before dismantling
or servicing the pump. Make sure the pump
is completely reassembled, the beltguard is
replaced, and all drain and ll valve and plugs
are closed before reconnecting the power
supply.
• Accidental starting or operation of the pump
while maintenance is in progress may cause
injury or damage.
• Lift only with the lifting eyebolts supplied with
the pump. Do not lift equipment attached to the
pump with the eyebolts supplied.
• 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 may
cause surface temperatures up to 220°F
(104°C).
• GEAR DRIVES UNITS: During operation,
gear drive units may become sufciently hot to
cause skin burns. Take care to avoid accidental
contact. After extended running, the lubricant in
gear units and lubrication systems may reach
temperature sufcient to cause burns. Allow
equipment to cool before servicing or performing
adjustments.
