Double Stage Rotary Vane Vacuum Pump

For more information on whether you need a single stage or double stage vacuum pump please reach out to an atlas copco expert.

Double stage rotary vane vacuum pump.

Improved oil anti suck back system to protect the vacuum pump in the event of sudden stop. Rotary vane vacuum pump 12cfm 1hp double stage hvac auto ac refrigerant air vacuum pump wine degassing milking medical food processing air conditioning vacuum pump the refrigerant vacuum pump is compact light and attractive in design. As the rotor rotates two vanes placed in rotor vane froove turn making contact with the internal surface of the cylinder due to centrifual force. The entire pump operation is interrelated and therefore not suitable for removing oxygen containing toxic explosive etched ferrous metals.

Two stage oil rotary vane pump mvp is two stage oil sealed rotary vane vacuum pump. Two stage rotary vane pumps are suitable for applications in the low and medium vacuum ranges down to a pressure of 10 3 hpa. 80 lpm to 95 m3 hr. Edwards range of rv rotary vane pumps.

Excellent ultimate vacuum and pumping speed with high performance. 1584 lpm ultimate vacuum. It was invented by charles c. Rotary vane vacuum pump is one of the main pumps to obtain low and medium vacuum pumps.

The two stage oil rotary vane pump is made of ferrous metal and is relatively accurate. Conversely if deeper pressure with good vacuum performance is necessary the dual stage rotary vane pump would be the best solution. It uses the big starting torque and is specially designed for low temperature environment. In the 5 21 m 3 h range pfeiffer vacuum also offers the pascal series as products with superior vacuum performance.

According to the r. Barnes of sackville new brunswick who patented it on june 16 1874. Nor can it be used as a compressor or delivery pump for various gases that chemically react with vacuum oil. Pumps belonging to the duoline series cover a pumping speed range of 1 3 to 300 m 3 h.

In short if vacuum level is not an issue a single stage vane pump may do the trick. The pump and motor are connected by flexible coupling. Double stage rotary vane vacuum pumps. It can be divided into oil seal pump and dry pump.

An integrated gas ballast feed allows condensable vapors to be pumped down. Two stage rotary vane pumps can be used in the pressure range between 100 hpa and a pressure roughly a decade above the final pressure.
