SHENOVAC OIL FREE DIAPHRAGM VACUUM PUMPS &
COMPRESSORS (Single & double Stage)
Diaphragm vacuum pumps / Compressors are completely oil less with
continuously rated built in motor. These are preferred due to their minimal
maintenance & compact size as compared to sliding vane type vacuum pumps
& reciprocating piston type air compressors.
SHENOVAC OIL SEALED ROTARY HIGH VACUUM PUMP is oil immersed, rotary vane
types. The main assembly consists of a main body with a rotor mounted
eccentrically in it. The rotor is provided with two vanes opposite each
other with springs in between, which press them against the inner wall of
the main body. When the rotor revolves, the vanes move-in and out of the
rotor and sweep the air space twice per revolution.
