The nXDS series has the latest technological advancements and greatest benefits.
The XDS is the traditional design proven for many years in the real world, and has the lowest initial investment.
XDD1 diaphragm pumps are used for backing small compound turbomolecular pumps in clean, high vacuum applications, and also designed to be free standing bench top units. A typical ultimate pressure of better than 5 x 10-8 mbar can be achieved when using an XDD1 to back a 70 l/s turbomolecular pump.
