Generalize:DSVP Series Varying Pitch Screw vacuum pump is composed of a pair of meshing variable pitch screw rotors which rotate in the opposite direction and synchronous way at high speed in the pump cavity to complete the intake and exhaust cycle. Varying Pitch Screw vacuum pump compresses the medium more efficiently with energy saving and lower temperature than constant pitch screw vacuum pump. Without any lubricants in the housing, it is perfect for medium recycling and environmental protection, which is the best upgrading products for oil-sealed, steam-jet and liquid ring pumps. The variable pitch screw rotor can be customized and manufactured in order to best fit for clients' requirements
