12KD Series

The 7KD series is unique high performance gas diaphragm which is particularly suited for gas / dust monitoring as well as industrial vacuum applications. The pump is fitted with internal damping chambers and resonanting membrane. The dual head arrangement further balances flow.

The use of high performance plastics facilitates use in high temperature applications such as combusion gas analysis. The overall construction is extremely robust.

Vibration mounts are fitted as standard.

This pumps is also available in a quad head arrangement (see 7KQ series).
