Diaphragm metering pump is a positive displacement pump designed to be used as a proportional metering pump. It uses a flexible diaphragm instead of a piston to vary the volume of the pump chamber, thereby increasing and decreasing the pressure of the internal fluid.
HAOSH diaphragm dosing pump’s sealed metering unit and corrosion resistant materials make it easy to pump all types of corrosive media.
how does a diaphragm metering pump work?
Diaphragm metering pump works on a similar principle to a piston pump. The diaphragm is driven up and down by means of an electromagnetic or electric motor. The plunger is fixed to the diaphragm, which pumps the fluid into the main stream. At the output, the volume of the dosed product is proportional to the amount of water driven.
Diaphragm dosing pumps are used in a wide range of applications, including water treatment, chemical processing and agricultural applications. Concentrates can be anything from fertilizers, water treatment additives and pharmaceuticals.
