This diaphragm pump is used to feed clayey water, slurry and many other kinds of liquid wastes to a filter press. Coagulations are obtained after such liquids are filtered under high pressure. The pump pressures can be raised to about 15 atm, and adjusted as desired depending on the liquid to be handled. It is also suitable for feeding high-density liquids containing chemicals and other substances over a long distances.
Unlike ordinary pumps, it has the piston section kept away from foreign matter. This ensures high durability and a long useful life for the pump.
Ball bearings are extensively employed in the parts which are subject to abrasion, making it easy to replace or service. The pump has come into popular usage for pollution control and where effluent from plants are treated.
