Application:

1.This series of pumps are used for pumping air in sealed vessels. It can be used alone, also can be used as the forepump, diffusion pump, and molecular pump.It can be applied to electronic vacuum device manufacturing, thermos manufacturing, vacuum welding, printing, plastic, refrigeration equipment repairment and instrumentation supportings. Because it has many advantages as small in size, light in weight, and low operating sound, thus is is more suitable for laboratory use.
2. At the ambient temperature range of 5~40 degrees and the inlet pressure is less than 10,the pump is allowed to be under long-term continuous operation.When the pumping gas relative humidity is over 90%,the gas ballast valve should be open.
3. Continuous flow pump inlet air operation shall not exceed 3 minutes.
4. Pump is not suitable for pumping gases which are corrosive to metal,easy to get chemical reaction with pump oil,or a gas containing dust particles, as well as the high oxygen, explosive, toxic gases.
