Horizontal screw pump Characteristic

1) There is no lubricating oil in the working chamber, so a clean vacuum can be obtained.

2) It adopts the latest generation of rotor profile with variable pitch and special shape, with uniform engagement, good sealing performance and high limit vacuum.

3) The air inlet pressure can work efficiently from 1pA to atmospheric pressure, and the air extraction efficiency is high, which can greatly simplify the vacuum system.

4) The exhaust end adopts the compound seal technology with invention patent, which is more reliable and has longer service life than the mechanical seal.

5) The pump cavity is a gap seal structure, which is not sensitive to a small amount of small particle dust.

6) A special cooling muffler has been developed, which has good silencing effect, low exhaust temperature, and is convenient for cleaning and blowdown.

7) The bottom exhaust and muffler low-level installation structure can ensure the smooth discharge of foreign matters in the pump and prevent the liquid accumulation in the pump cavity.

8) The rotor is processed and formed in one time, with high precision. The G1 level dynamic balance test is carried out, and the vibration of the pump is small during operation.

9) According to different working conditions, the surface of rotor and pump cavity can be coated with many kinds of anti-corrosion coatings, and duplex stainless steel can also be used as the material of rotor and pump cavity, which can greatly improve the anti-corrosion ability of vacuum pump, thus prolonging the service life of vacuum pump.

10) Equipped with advanced cooling system, it can accurately control the pump temperature and reduce the corrosion of chemicals to the pump.

11) The pump adopts a closed structure to avoid the leakage of lubricating oil due to the wear of dynamic seal.
