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 eletronics) is another impressive feature that makes it even more reliable.

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.
