This submersible pressure-switch operated water pump is the solution for a working system. Standard pumps basically transfer from A to B, this pump has the features detailed below, allowing the operator to work with the water away from the pump & when stopping the pump is necessary the pump will sense when demand for water has stopped & will then shut down. On sensing a drop in the water pressure in the discharge line the pump will start automatically thus eliminating the need for the operator to walk back the pump / starter to start & stop the pump. In addition there is also automatic control of the pump in low water level conditions, ensuring the pump does not run dry. The pump runs off a single phase supply. Submersible pumps with built-in integrated electronics designed to automatically start & stop the pump & prevent against dry running. Can be used as a water butts pump or with a rainwater tanks. Built-in electronic pressure switch & flow sensor Equipped with dry-run protection & built-in non return valve Easy to use High reliability Available with 3 or 4 impellers Supplied with 15 metre power cord Available with screen filter or stainless steel ring for use of suction kit To protect the pump & subject to the system operating cycle it may be necessary to include an expansion vessel in the discharge pipe from the pump. Performance Range Flow rate up to 120 l/min (7.2 m 3/h) Head up to 42m Restart Pressure: 1.5 bar Application Limits: 5m maximum immersion depth Maximum heigh between pump & point of use 10m Maximum liquid temperature +40 C.
