Double Diaphragm Pumps

Double diaphragm pumps are positive displacement pumps, each stroke moves the same volume of fluid. As the pump runs faster the flow increases.

Air operated double diaphragm pumps have a wide range of uses and our found in most industrial environments pumping a whole range of liquids from acid to food.

 

Diaphragm pumps have many advantages including excellent suction, variable speed/flow, compact, suitable for wide range of viscosities and liquids, hygienic options, ATEX approved, low cost compared to other positive displacement pumps.

The key disadvantages are that they cause a surge of liquid or pulsation which can interfere with some processes, they are under constant mechanical wear which gives them higher maintenance costs.

Due to the common nature of double diaphragm pumps there is a wide range of manufacturers in the market and many companies find they have double diaphragm pumps made by several different manufacturers.

Our principle brand is DEPA double diaphragm pumps, they have an excellent design with an exceptional air valve construction, they offer a fantastic range including hygienic pumps, powder pumps, high pressure pumps and ATEX pumps.

Despite having the excellent DEPA range we realise that we must also be able to offer other brands such as ARO, Sandpiper, Wilden, Blagdon, Yamada etc.

Our double diaphragm pump prices are competitive and our deliveries are quick.
