Rsd120 Dry Screw Vacuum Pumps

RSD Dry Screw Vacuum Pumps

The dry screw vacuum pump is an best oil-cost-free pump which is popular in modern several years. It is advantages are which includes compact construction, higher pumping velocity, large vacuum degree, no friction on functioning components and long service daily life.It can also suck air which is corrosive, harmful, dusty and containing condensable vapor. The principal components of the pump are a pair of massive-pitch screws with opposite directions and a pair of higher-precision challenging-toothed gears. Depending on a pair of reverse-rotating screws, a certain gap is maintained.CZPTn by a pair of synchronous gears,not only the screw is maintaining a certain gap with the pump human body,but also the outer diameter of a screw maintains a specified gap match with the base diameter of the other screw.Our RSD dry screw vacuum pumps adopt unique screw technologies and major higher-efficiency push engineering, attaining innovative temperature manage, long maintainance intervals and much better pumping overall performance, making sure the customers making the most of long-phrase lower functioning charges.

1. The screw of the pump adopts a single-head CZPT pitch rotor and the large-efficiency rotor profile layout,which has the attributes of higher final vacuum.

2. There is no lubricating oil in the pump chamber,reaching high thoroughly clean vacuum.It can also be blended with Roots pump to type a dry pump device.

three. The pitch rotor which is processed by innovative products has function of excellent geometric symmetry, with good efficiency of lower sound and long daily life.
