The Jet self-priming centrifugal pumps are particularly suitable for water supply in domestic installations and for small agricultural applications, in gardens, small-scale industry and wherever a pump with self-priming function is required. The pump has an excellent suction capacity, even if there are air bubbles in the water. The pump body is cast iron and the impeller, diffuser, venturi tube and injector are techno polymer. It is suitable for pumping water with a low content of sandy constituents. This Jet version is equipped with a CONTROL-D device for the control and protection of domestic pumps without a diaphragm tank. This CONTROL-D has built-in flow and pressure measurement that automatically starts the pump when one or more taps are opened and automatically stops when a water shortage is measured. The pump will continue to operate as long as there is water consumption and the water pressure is kept constant. The pump automatically stops after 10 seconds if all taps are closed. If there is a shortage of water, the pump stops and a red LED appears on the display. The pump can be restarted with the reset button. Show more
