Jet Pump

Jet Pump

The most remarkable character of the jet pumpis a Venturi system in its pump body. It achieves self-priming function byusing Venturi system in its chamber as well. The total fluid produced by its centrifugalimpeller is sent only partly to the delivery outline, the rest is circulatedand jet it through the nozzle in its Venturi system, thisspeed flow leads the water in suction chamber and generates the necessaryvacuum to self-prime the pump.

The change of jet pump power needing is smooth while the head change fromlowest to highest smoothly making more reliable to use. Its construction issimple and easy to maintain, suitable for gardening, water supply, increasewater pressure and other applications, designed to pump clean water or othernon-aggressive fluids. It is usually combined with a pressure switch and asurge tank to be used as a domestic water system for distributing water.

The self-priming jet pump is suitable forsuction in 8-9 m depth,specifically water with air and/or gas. The maximum temperature of fluidflowing must be 50ºC and its maximum working pressure should be 10 bar. The jet pump must be installed in enclosed places orprotected against inclement weather. A check valve with a filter in itssuction-end must be installed. It has one year warranty.

Motor of Jet Pump
The jet pump is attached with induction motor directly and it has two poleswith a speed of 2800r/min. It has insulation class B with class F available onrequest and protection degree IP44 with IP 54 optional as well. Its standardpower source has a voltage of 220V 50Hz for single phase with less than 2.2kWand 110V, 115V, 127V, 60Hz for single phase with less than 1.5kW. It hasdual-voltage 110/220V 60HZ for power less than 1.5 kW. All models of jet pumpsare available in three phase.

Materials of Jet Pump

The jet pump case and the motor front cover aremade of cast iron. Its impeller is plastic Noryl or it can be brass uponrequest while the motor casing is made of aluminum alloy. Its shaft can be 45steel or stainless steel on request. The jet pump rotary face is made of carbonwhile the stationary face can be ceramic or silicon carbide on request.
