Product information

The screw vacuum pump unit is mainly composed of a main engine, motor, oil and gas separator, cooling fan assembly, cooling waterway system and unit base. At the same time, it adopts a customized high-efficiency motor and drive system with sealing technology, which greatly reduces power consumption and runs. Low cost; It also has the advantages of low noise and simple installation and operation. The low noise makes it less impact on the workplace and the environment. Even if a muffler is not used, it is believed that the special spiral rotor design can achieve extremely quiet and low-vibration operation.

Rated power 5.5 - 110 kW Extraction speed 180 - 1500 m ³/hr Limit pressure 0.02 - 0.01mbar

characteristics

  • screw rotor

The rotor profile meshes evenly, has good sealing performance and high pumping efficiency;
The rotor is subjected to G1 level dynamic balance test, and the pump operates with little vibration.

  • Exquisite design and manufacturing

Short exhaust path reduces foreign matter deposition during manufacturing;
The sealed structure is adopted to avoid leakage of lubricating oil caused by wear of dynamic seals.
