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 membrane tank. The booster system features a dual outlet selection for easy installation and a pressure tank to reduce water hammer in the piping.

JP 4-47 PT-H offers the comfort of constant water pressure with automatic start and stop. This is controlled by the combined pressure switch and pressure tank which ensure optimal start/stop of the booster system according to 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 case 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 long life. This booster unit guarantees optimal self-priming properties, with a suction height of up to 8 metres. The self-priming pump also ensures stable operation as it is capable of lifting liquid from below the inlet level and can handle a mixture of air and liquid until the pump reaches a fully primed pumping condition.

The JP pump has built-in thermal protection, which immediately stops the pump if it overheats. The motor is air-cooled and equipped with oversized ball bearings, sealed and greased for life to ensure quiet operation and minimal service.
