This Edwards QDP-40 Dry Vacuum Pump is a four-stage, positive displacement rotary pump. These "Dry Pumps" are ideal for the corrosive enviroment of semiconductor processing. The applications range from light duty loadlock and sputtering to demanding processes including plasma etch, LPCVD, PECVD, and MOCVD.
Every dry vacuum pump we sell goes through a rigorous rebuild process at our Albuquerque, New Mexico (NM) location. Each pump is fully dismantled and all parts are decontaminated and inspected. Damaged or worn parts are replaced. All bearings, o-rings, seals, and gaskets are replaced. Rebuilt pumps are attached to our computer controlled pressure diagnostics system where their performance is monitored for 72-hours under varying load. Pumps are leak tested to ensure safety during operation. Final pump is cleaned and painted as required.
