Hygienic Diaphragm Pumps

The FDA states that in order to be food grade, the food contact surfaces of a hygienic pump need to be smooth, free of cracks and crevices, non-absorbent, cleanable, non-toxic and corrosion resistant to ensure that no food or bacteria can harbour and contaminate the product.

Clean in Place (CIP) is the ability for a pump to be easily taken apart, cleaned and sterilised without having to remove it entirely from the installation. This is of high importance for food processing pumps and those used in pharmaceutical industries where the product is to be used for human consumption.

Food grade pumps are constructed of materials that the FDA states are safe for human consumption. This is usually sufficient, however we also supply 3A and EHEDG models where the actual pump design has been reviewed and certified as meeting hygiene standards safe for use as a food industry pump.

All products that we offer for food, cosmetics and pharmaceuticals are as a minimum constructed of FDA approved materials for human consumption. Where more stringent approval is required, we also offer pumps certified to 3A and EHEDG.

The pump is made up of two chambers. As the air forces the diaphragm to move in to the one chamber it forces the fluid inside into the outlet, whilst the other chamber fills up with fluid drawn from the inlet. As the diaphragm moves back into the opposite chamber, the fluid now in that chamber is forced out and the other chamber begins to fill up.
