DESCRIPTION
EVDR series The EVDR-series are Oil Free Rotary Vane vacuum pumps and compressors. Eurovacuum EVDR-series pumps & compressors are 100% oil less operation, Single Stage, Air-Cooled and Direct Driven. They have self-lubricated long life vanes and have a quiet operation. Pressure regulator valves are included in the standard supply. Due to the oil free operation these pumps are ideal for Industrial applications that need easy installation and little down time for service. Operating principle A rotor is positioned eccentrically in the pumps cylindrical housing. The free moving vanes are inserted into their rotor slots. When the rotor turns the centrifugal force pushes the vanes against the cylinder wall and creates a pocked of air between the rotor and the cylinder. As the rotor continues to turn the air pocked volume between the blades changes due to the eccentrically positioned rotor. From the inlet to outlet the chamber volume becomes bigger and then becomes smaller again. This way the pump is compressing the air from the inlet to the outlet. When the inlet of the pump is connected to a closed volume the pump is used to make a vacuum. When the inlet is connected to the atmosphere the pump can be used as a compressor to make compressed air.
