Diaphragm Pumps

Diaphragm pumps use a positive displacement design rather than centrifugal force to move water through the casing. This means that the pump will deliver a specific amount of flow per stroke, revolution or cycle. For use in applications where shallow depths and slurry water render centrifugal pumps ineffective. The most popular are the 2 and 3 inch range producing flows in the range of 50 to 85 gallons per minute (GPM). They have the ability to handle air without losing their prime and of handling water with a solid content greater than 25% by volume. Available to hire from depots nationwide.
