Refurbished Edwards QDP40 Dry Pumps
The Edwards QDP Series Dry Pumps are an excellent choice for primary pumping requirements in a wide range of applications. Their low capital and repair cost, ease of operation and interface ability with a wide range of process tools make them the preferred choice for upgrading rotary vane pumping systems.
Following the 1st generation of air cooled Edwards CDP and DP series dry pumps, the QDP40 was launched featuring a more quiet water cooled motor and built in functionality for integration to a parent system. This 2nd generation of dry pumps from Edwards became the work horse of the semiconductor Industry in the mid 90’s, and many thousands are still in use today.
Mechanically, the QDP40 shares essentially the same pump module as its predecessors, as well as its successor, the iQDP. The QDP gas purge system, while functionally similar to the iQDP as well, is set and adjusted manually. The QDP electrical and electronic controls and sensors are provided by separate control modules available in varying degrees of sophistication.
