How Does A Two Stage Rotary Vane Vacuum Pump Work

The pump rotor is mounted eccentrically in the pump cylinder.

How does a two stage rotary vane vacuum pump work. The standard lubricated rotary vane pump is a single stage pump with an integral closed loop oil circulation system. Model 400 14. The centers of these two circles are offset causing eccentricity. The rotary vane vacuum pump is an oil sealed vacuum pump meaning that the evacuation chamber is filled with a specifically formulated mineral oil which acts as a sealant and lubricant between the vanes and vacuum pump chamber housing.

21 cfm 36 m3 hr. According to the r. The free moving vanes 4 are inserted into a numerous rotor slots 3. Rotary vane vacuum pumps come in either one stage or two stage.

Two stage rotary vane vacuum pumps operation and maintenance manual model 800 28 800 l min. Rotary vane vacuum pump is one of the main pumps to obtain low and medium vacuum pumps. It can be divided into oil seal pump and dry pump. 28 cfm 48 m3 hr.

Model 600 21 600 l min. A rotor 2 is positioned eccentrically in the pump cylindrical housing 1. Lubricated rotary vane vacuum pump. When the rotor turns the centrifugal force throws the vanes against the cylindrical wall and creates a chamber between the rotor and the cylinder.
