EVP series oil free dry scroll vacuum pump is comprised by pump head, motor and basement. The pump head including fixed scrolls, orbiting scroll, main shaft, cooling fans, crank shaft kits, and bracket.
It contains two spiral cylinders, one offset and orbiting against the other with an offset of 180°. Thus several crescent-shaped pockets of differing sizes are created. By means of an eccentric drive, the orbiting scroll orbit surround the fixed scroll, reducing the volume of the pockets and compressing gases from the outside towards the inside. Thereby, pumping the gases from vacuum chamber.
