  Deep Well Pump Working Principle: The JDW pump comprises ejector unit and a centrifugal pump. The ejector unit in the fact is a Ventrui system consisted of a tube and a nozzle, lowered in a 4" well and connected to the pump body by tow pipes. The total delivery produced by a centrifugal impeller is sent only partly to the delivery outline. The remaining water is circulated and jet through the nozzle in Ventui system. With tremendous speed, this flow lead the water in the well and delivery toward to the ground. By the suction of the centrifugal pump, the water came in to the pump and gain a energy through the impeller, and once again, partly of the water return to the Venturi system through smaller pipe and circling. The ejector unit can be installed directly on the pump body works like JET Pump.
  These pumps are suitable for pumping clean water and chemically non-aggressive fluid. They are extremely reliable, economical and simple to use, finding many uses in domestic applications and the automatic distribution of water from small and medium-sized surge tanks from a automatic booster systems to supply water. To ensure adequate counter-pressure, It is always to install a foot value with a filter on the suction opening.
  These pumps should be installed in a covered area, protected against the weather.
