As we know that Stokes pump is very well known for its performace.

EVP can also provide ESP-70G&ESP-150G to drop-in replacement stokes 212H and 412J. 100% replace from performance to dimension as well as 100% spare parts. That means you can use EVP spare parts directly to stokes pump.

ESP Series Piston Vacuum Pump is a single stage rotary piston vacuum pump, namely sliding vane vacuum pump.

Applications:
It’s suitable for vacuum smelting, vacuum drying, vacuum coating, electrician, electron, metallurgy, chemical industry, ceramic, aviation, laboratory and other occasions of vacuum coating, vacuum drying, vacuum degassing, vacuum impregnation, vacuum brazing, vacuum heat treatment, vacuum concentration, vacuum reaction, high altitude simulation experiments on the vacuum operation ,etc.
It can be used individually and also combined together with the fore-pump of other high-vacuum pumps such as Roots pump, oil diffusion pump and molecular pumps, etc. It’s necessary to add additional devices please, (such as filter, gas-water separator and 1# vacuum oil) in case that gas contains high volume of oxygen, explosive, erosive to ferrous metals, chemically reactive to vacuum oil and more water or dust.
Features:
