Marine Sewage Treatment Plant Plunger Piston Metering Dosing Pump

The dosing pump is used for feeding chlorine into the chlorination tank. 

The pump head consists of poly tetrafluoroethylene rollers, which are driven by an electric motor through a reduction gear.

The liquid in the plastic container is pumped to the chlorination tank when a nylon pipe is pressed gradually by the rollers. During operation of the pump, one of the rollers must always contact with and press on a certain point of the nylon pipe to act as a non-return part.
