Dry Scroll

In addition to providing Dry Scroll Vacuum Pump Rebuilds, PTB Sales can also offer NEW Dry Scroll Vacuum Pumps as we are an Authorzied Distributor for ANEST IWATA.

Dry scroll pumps are used for small scale vacuum applications where there is a need for contamination free "dry" vacuum as there is no oil used in the pump.  Scroll Pumps employ a tight tolerance, rotating scroll to squeeze gas from the inlet to another stage or exhaust. Scroll Pumps can attain a pressure of 7x10-3 Torr at a pumping speed of up to 20 cfm. Dry scroll pumps can be used for corrosive and oxygen service, but are not recommended for applications which have high amounts of water vapor.

Our rebuild process involves factory training and specified tooling for the necessary precise required for alignment that lasts the life of the scroll pump. Please call for scroll pump model recommendations for your application.
