Vacuum Pump Operating Information
To protect the vacuum pump from premature failure it is important that the following
procedures be adhered to;
Maximum Pressure
The maximum allowable pressure is not exceed -40kPa. Exceeding this value will cause the
pump to overheat causing severe damage and voiding warranty.
Operating Temperature
The vacuum pump surface will become extremely hot during operation. Care must me
exercised when coming in to contact with the surface of the pump or any other items likely to
become affected by heat.
Vacuum pump performance is affected by the ambient and inlet temperatures. Vacuum
pumps must not be operated where the inlet temperature exceeds 50
o
C. As the inlet
temperature approaches 40
o
C the vacuum pump must operate at a reduced duty cycle
allowing time for adequate cooling of the pump between cycles. Duty cycle is determined by
ambient temperature. The higher the ambient temperature the shorter the duty cycle.
Vacuum pumps expel hot air at high velocity. Adequate provision must be made to allow for
the safe and unrestricted expulsion of the exhaust air.
DO
• ensure that there is adequate space around the vacuum pumps to allow a free flow of
air on all sides. We recommend a least 1m of free, unobstructed space on all sides.
• keep vacuum pumps clear of debris.
• check correct function of relief valve regularly.
• consult with specialists if you intend to duct exhaust from the pump. Incorrect ducting
will affect vacuum pump performance and can lead to failure of the pump and
overheating leading to injury or fire.
DO NOT
• exceed the maximum operating pressure.
• exceed the maximum inlet operating temperature.
• block the exhaust manifold.
• place objects in close proximity to the exhaust air.
• place vacuum pumps in confined spaces.
• enclose the vacuum pumps in enclosed spaces.
• place vacuum pumps under machines unless absolutely necessary. This will result in
limited air flow around the pump causing premature failure and a drop in performance
and cause surrounding machinery to become affected by heat.
• touch the surface of the vacuum pump as it will become hot during operation
resulting in burns.
• move the vacuum pump from its originally installed location.
Failure to follow these instructions will void your warranty
