PRODUCT DATA SHEET XDD1 DIAPHRAGM VACUUM PUMP XDD1 diaphragm pumps are compact and efficient pumps, 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 ls-1 turbomolecular pump. The XDD1 pumps are intended for use on non-aggressive, safe area applications. The 24 V version is designed to provide a complete pumping package and can be used with the Edwards Turbo and Instrument Controller (TIC). The d.c. voltage motor runs on 24 V via a 15 pin DIN connector. By selecting the appropriate mode the pump speed can be controlled by the user to provide variable pumping speed or max pumping speed. The pump is a compact and efficient. The Mk3 24V version can now be user set to run at a maximum speed of 1.8 m3h-1 running at 2400 rpm. Under normal conditions the XDD1 is virtually maintenance free, the lifetime of the diaphragms and valves is typically > 10,000 operating hours, depending on the application.
