The air is drawn into the pump due to the negative pressure created by the moving impeller and is emulsified with the liquid contained in the pump casing. The air liquid emulsion is forced into the priming chamber where the lighter air is separated and leaves through the discharge pipe; the heavier liquid drops back down into circulation. Once all of the air has been expelled from the suction pipe, the pump is primed and works like a normal centrifugal pump. The pump can also work with an air-liquid mixture. The non-return valve has a dual function: it prevents the suction pipe from emptying when the pump is off; in the event off accidental emptying of the suction pipe, this holds a sufficient amount of liquid in the pump casing to prime the pump. The discharge pipe must be free to expel the air coming from the suction pipe.

Sakuragawa submersible drainage pumps enjoy world-wide acceptance based on their comprehensive range of reliable, robustly manufactured products, produced in their new state of the art facility at Fukui, Japan. Experience gained over a fifty-year period in diverse industries, is reflected in the product range which can be found operating successfully in the following applications:
Mining: open cast and deep operations
Industrial: drainage, recirculation, waste water etc
Marine: dry dock, ship services and facilities
Food or Chemical:

Madoda Pumps

The Madoda 80mm is a mechanically driven diaphragm pump. The unit has no mechanical seals, packing etc. This enables the pump to handle highly abrasive liquids, large solids and slurries. The pump can run dry indefinitely with suction lift of up to 6 meters.


Electric & Diesel Diaphragm Pumps


  • Mining - dewatering, cleaning of dams, slurry & sludge transfer solids up to 40mm

  • Construction - dewatering, slurry transfer

  • Agriculture - liquid manure, animal food, fertilizers, blood and chicken pieces

  • Environmental - clean-up operations, oil spillages etc.

  • Waste Water - sewage, effluent, fibres & rags


  • Can run dry indefinitely
