Marine Doshing Pump For SWCB type Sewage Treatment Plant:
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.
