CM Compact Diaphragm Pumps

Specialized diaphragm pumps for difficult media

ABEL CM piston diaphragm pumps are single or double-acting pumps that are used for difficult media. They are highly resistant to wear, even when used at high pressures over an extended period of time. Their true double-diaphragm technology offers a high degree of safety. When used as a pump for feeding filter presses, the rugged, automatic flow rate control (which does not use complex electronics) is another impressive feature that makes it even more reliable.

The advantages of design

The CM technology has optimal design to withstand high pressures, maximum filling efficiency and is hermetically sealed. In addition, the pump has a safety valve and automatic liquid supplement in the primary circulation. Moreover, the CM can run dry.

ABEL piston diaphragm pumps have built our reputation as a leading manufacturer of reciprocating positive displacement pumps, establishing ABEL as the world market leader in filter press feeding.
