Product Description

DPS Air Cooled Dry Screw Vacuum Pump:

DPS dry compound screw vacuum pump is the innovation and development of AfaPa's products, using the fifth generation of compound variable pitch screw technology (30% energy saving, low exhaust temperature), with high efficiency, energy saving, environmental protection, lightweight, easy operation, reliable performance characteristics. It will be main developing trend of the vacuum pump in future.

Working Principle:


Dry compound screw vacuum pump are consist of two paralleled screw rotors and pump body form multiple sealed space, rotor and rotor, rotor and pump body all keep minuscule clearance(no touch, no friction), with the reverse gears driving, gas keep continuously transfer from inlet hole to outlet hole. Due to two rotors and pump body have no friction each other, need not lubrication oil, can keep clean gas. Gas keep continuously transfer, short passageway, high efficiency, outlet hole position lower than screw rotors, strong drainage ability, easy to clean, no intermediate bulkhead(claw vacuum pump and rotors vacuum pump have intermediate bulkhead), better exhaust and drainage, easy to maintain.
 

Our Advantages

1. Air cooled design.
2. Working chamber 100% no oil.
3. Strong resistance to water vapor.
4. Newest variable pitch screw rotors.
5. No contact double screw rotors.
6. Self-design multistage flat seal.
7. Max vacuum reach at 1Pa.
