RSD Dry Screw Vacuum Pumps

The dry screw vacuum pump is an excellent oil-totally free pump which is common in latest many years. It’s positive aspects are including compact structure, substantial pumping pace, large vacuum degree, no friction on operating areas and prolonged provider lifestyle.It can also suck air which is corrosive, harmful, dusty and containing condensable vapor. The main elements of the pump are a pair of big-pitch screws with reverse directions and a pair of large-precision tough-toothed gears. Based on a pair of reverse-rotating screws, a certain gap is maintained.CZPTn by a pair of synchronous gears,not only the screw is trying to keep a particular gap with the pump body,but also the outer diameter of a screw maintains a particular hole match with the bottom diameter of the other screw.Our RSD dry screw vacuum pumps adopt special screw technological innovation and foremost substantial-performance push technological innovation, achieving innovative temperature handle, extended maintainance intervals and far better pumping overall performance, ensuring the consumers taking pleasure in extended-time period low working costs.

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

two. There is no lubricating oil in the pump chamber,attaining higher thoroughly clean vacuum.It can also be merged with Roots pump to type a dry pump unit.

three. The pitch rotor which is processed by innovative gear has feature of great geometric symmetry, with good efficiency of low sounds and prolonged lifestyle.
