Features and uses:
Product Features:
◎It adopts equal pitch and variable pitch screw, high inspiratory exhaust efficiency, low exhaust temperature, low power consumption, low noise and low vibration.
◎ has high vacuum performance, ultimate pressure: 1 * 10-2 Torr (Torr).
◎Simple structure, no metal contact on rotating parts, easy maintenance, low maintenance cost and long service life.
◎The working chamber and screw surface are coated with Teflon, nickel or Hastelloy for a wide range of applications.
◎The gear transmission part is immersed in oil lubrication, and the bearing adopts forced lubrication to ensure the lubrication reliability and greatly prolong the maintenance period of the bearing.
◎ Multi-pass lip seal design reduces the probability of simultaneous seal failure and effectively prevents leakage. The nitrogen pressure protection prevents the erosion of the seal by the pumped gas and prolongs the service life of the seal.
◎ No oil or water medium, no pollution to the pumping gas.
