Diaphragm Pumps for Continuous Flow Cryostats

Diaphragm Pumps for Continous Flow Cryostats

Overview

Overview

The Edwards XDD1 diaphragm pumps are used for backing small compound turbo-molecular pumps in clean, high vacuum applications. They comply with EN61010 and EN1012, and are 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-1 compound turbo-molecular pump.
 
The a.c. voltage motor can be used on worldwide supplies ranging from 100 to 115 V, and 200 to 230 V. The pump has both an on/off and voltage changeover switch. The power is connected through a standard EN60320 socket.
 
This pump is NOT supplied with connection cables and is factory set to 230 V. A suitable cable should be ordered with the pump.
