Grundfos JP 4-47 PT 60L self-priming pump Cod. 99594664

Self-priming pump with pressure switch and expansion vessel JP 4-47 PT-H AA-BBVP

Product code 99594664

The Grundfos JP 4-47 PT-H consists of a Grundfos JP pump, a pressure switch, a pressure gauge, and a 20-liter Grundfos GT-H horizontal diaphragm tank. The booster set features a dual-outlet selection for easy installation and a pressure tank to reduce water hammer in the pipework.

The JP 4-47 PT-H offers the convenience of constant water pressure with automatic start and stop. This is controlled by a combined pressure switch and pressure tank, which ensure optimal start/stop of the booster set based on demand. The pressure tank limits the number of start/stop routines, as the water stored in the tank can be used without starting the pump in the event of low water consumption or leaks. The cut-in pressure is set to 2.2 bar.

The design is robust and constructed of corrosion-resistant materials to ensure a long life. This booster set guarantees optimal self-priming properties, with a suction lift of up to 8 meters. The self-priming pump also ensures stable operation as it can lift liquid from below the inlet level and handle an air-liquid mixture until the pump reaches a fully primed pumping condition.

The JP self-priming pump has a built-in thermal protection that immediately shuts down the pump in the event of overheating. The air-cooled motor features oversized, sealed, and greased-for-life ball bearings to ensure quiet operation and minimal maintenance.
