FAQs

A dosing pump, otherwise known as a metering pump, is designed to very precisely deliver a specific quanitity of fluid to a container, tank or fluid stream at controlled intervals.

Dosing pumps are able to provide precise metering through their smooth, pulsation free operation and ability to achieve extremely low flow rates whilst maintaining accuracy.

Thanks to their accuracy at low flow rates and smooth pumping, peristaltic pumps, progressive cavity pumps and diaphragm pumps and lobe pumps are most commonly used in dosing systems.

Metering pumps are typically used to accurately delivery ingredients, additives and chemicals in food, process and water treatment industries.

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.
