Bdr (2XZ-C) Double Stage Rotary Vane Vacuum Pump for Refrigeration

Pump character:

1: Double stage and high speed directly connected structure.

2: Equipped with specially designed air ballast valve to prevent water mixing with oil pump and prolong pump working time.

3: Adopt international similar product design,small size,light weight,low noise,easy to start,long time stable operation.

4: No oil leakage, no oil injection and environmentally friendly.

5: The pump can be used as a suction pump alone, also can be used as a backing pump for booster pump, diffusion pump and molecular pump,also can be used as maintenance pump or forepump in the system.

6: It is widely used in the electric vacuum device manufacturing industry, refrigeration industry, medical analysis device industry, solar energy industry, electric light source industry, vacuum furnace industry and scientific research unit.

Pump specifications:


Application:
 
1. The pump is one of the basic equipments to exhaust a sealed vessel. It can be used either independently as main and can also be served as forepump for booster pump diffusion pump and molecular pump or as holding pump for a vacuum system and as a pre-pumping for different kinds of the pumps. So that is can be applied in electro-vacuum industries, vacuum flask manufacturing, vacuum welding and as an accessory to those fine gauges or meters where vacuum is required .It is more suitable for laboratory use because of its small size ,less weight and quiet operation .

2.The pump is allowed to work continuously for many hours at a stretch under atmospheric temperature of 5ºC-40ºC and intake pressure below 1230pa.While the pumped gas containing moisture of a relative humidity of more than 90% gas-ballast valve should be open.

3. Whit the inlet port widely opened to atmosphere the pump is not allowed to work more than one minute.

4.The pump is not suitable for pumping over-oxidized, poison, explosive and corrosive gas as well as gases which react chemically with the pump oil contain particles of dust.
