Diaphragm Pumps
Darcy diaphragm pumps are reciprocating positive displacement pumps designed for difficult transfer duties where solids, fibres or rags may be present in the liquid. Their coupling-rod design allows them to handle larger solids while maintaining reliable pumping performance.
The pumps can run continuously when dry and prime quickly, making them a practical option for demanding spill response and industrial applications. Petrol, diesel and electric power options are available to suit different site requirements.

Product Details
Product Information
Darcy diaphragm pumps use a coupling rod driven by a gearbox speed reducer to create the reciprocating pumping action. This design allows the pump to handle liquids containing fibres, rags and solids without relying on rotating parts in contact with the liquid.
The range is designed for fast priming and strong dry-running performance, making it useful where pump conditions can change quickly or where the liquid being transferred contains difficult material.
