Regarded as one of the best surface pumps for deep well water priming. It consists of two pumps connected in series, one is the ejector pump and the other is the centrifugal pump. The ejector pump is lowered in a 4" or smaller well / bore and connected to the centrifugal pump body by two pipes.
Usually these pumps are used with a set of Auto tank system including the tank, the pressure gauge, the pressure switch and the foot valve, etc. The Auto tank system is another significant merit of this pump which makes the pump more convenient.

The convertible jet pump with pressure switch is suitable for shallow or deep bore wells up to 20 meters deep. The pump comprises of an ejector unit and a centrifugal pump.
The most remarkable characteristic of this pump is it can be used to supply clean water from a relatively deep well. It is also suitable for chemically non-aggressive fluid.

Feature
High head, high suction head and low enery consumption, high efficiency and low cost maintenance, flat operating curve, with relatively simple construction. It is reliable and safe to use. To ensure the adequate counterpressure, it is always installed with a foot valve with a filter on the suction opening.
The convertible deep well jet pump is a clean water pump consisting of pump, mechanical seal and single-phase asynchronous motor, the key part, ejector, hosed in the jet body which can be installed directly on the pump body or more often lowered in a well and connected to the pump body by two pipes, are suitable for suction from deep wells.

Ideal for deep or shallow bore or well providing water for a domestic supply. Suitable for continuous duty. Closed and externally ventilated. The jet pump works well if you pump water from your bore or well into a tank and then use a pressure pump to transfer the water from the tank to the house or taps.]

The Convertible Jet Pump and can also be set up to supply the whole house from a well.
If you can match the flow of the bore to the output of the pump you could run the Convertible Jet Pump all day, every day, without any problems of it running dry.
The pressure switch is supplied to enable easy conversion to automatic operation and is preset at 1.1 Bar (15.4 PSI) to 1.9 Bar (26.6 PSI).
19L pressure tank air pressure is 1.5-1.8Bar, (21 PSI – 25 PSI) max pressure is 8bar (112 PSI).
If you intend to make it automatic, these Convertible Jet Pumps do not get fitted with an electronic pump control.
The Convertible Jet Pump is better suited set up as a pressure system and you would have more control over the settings VIA the pressure switch that is on the pump.
