Product advantage
Summary of advantages
1.There is no oil in the pump chamber, which does not pollute the vacuum system, improves product quality, solves the problems of oil emulsification and frequent replacement of working fluid, maintenance and upkeep, and saves usage costs.
2.A single pump can reach 5pa, and can be connected in series with Roots pumps,
molecular pumps, etc. to form an oil-free unit with higher vacuum degree.
3.The vacuum degree and pumping rate are not affected by water temperature and ambient temperature, and the performance is stable.
4.The pump chamber, screw rotor and other overcurrent components can be coated with nickel phosphorus and infiltrated with Hastelloy alloy, which can remove corrosive media and is particularly suitable for product distillation, drying, degassing, etc. in chemical and pharmaceutical processes.
5.The extracted gas is directly discharged from the pump body without environmental pressure, making gas solvent recovery more convenient.
6.Easy to clean. When dirt enters the pump chamber and needs to be cleaned, simply open the pump's suction and exhaust ports. After starting the pump, add an appropriate amount of water or cleaning agent from the pump's suction port to clean the pump without disassembling the entire pump.
