The slide valve vacuum pump is widely used in vacuum coating, vacuum heat treatment, vacuum sintering, molecular distillation and simulation experiments.

The oil-free dry vacuum pump can better replace the rotary vane vacuum pump and slide valve type vacuum pump.

Roots pump is widely used in vacuum casting, vacuum melting, vacuum degassing, vacuum coating, vacuum distillation, vacuum drying and so on.

Roots Pump Sysems With Screw Vacuum Pumps

Better performance: Zero flow compression ratio, High vacuum limit, High reliability.

Roots pump systems with rotary piston pumps have features of obvious effect of saving energy, high vacuum and high pumping speed in high vacuum. It is widely used for transformer and electrical wire of electric utility industry, vacuum soaking and vacuum drying of capacitor.

Reciprocating Vacuum Pump also known as piston vacuum pumps, is one of the low vacuum equipment.

It is suitable for the high vacuum distillation, vacuum evaporation and dehydration of the pharmaceutical industry, the vacuum drying and impregnation of the electrician and the light textile industry, and the freeze drying of the food industry.
