Pumps / Dosing Pumps

Diaphragm pump

Dosing pump to meter small doses of low viscosity and/or corrosive products.

The simple and reliable diaphragm dosing pump is designed for dosing liquid additives, disinfectant products (acid, soda, detergent...) for cleaning in place applications. The pump is composed of a membrane connected to a piston which alternating movement successively fills and empties the pumphead.

The backward movement of the membrane opens the bottom check valve and allows the entry of fluid, which fills the pumphead.

The forward movement of the movement closes the bottom check valve, opens the top check valve and expels the dose.

Simple and robust construction
