Grundfos JP 5-48 PT-V consist of a Grundfos JP pump, a pressure switch, a pressure gauge and a Grundfos GT-H 18-litre vertical diaphragm pressure tank. The pressure tank reduces water hammer in the pipework.

The JP 5-48 PT-V provides the comfort of constant water pressure with automatic start and stop. This is controlled by the pressure switch and pressure tank combined ensuring optimal start/stop of the booster set according to demand. The pressure tank limits the number of start/stop routines, as water stored in the tank can be used without starting the pump in cases of low water consumption or leakage loss. The cut-in pressure is set to 2.2 bar.

The design is robust and built upon corrosion-free materials to ensure a long lifetime. This booster set ensures optimum self-priming properties, featuring a suction-lift up to 8 meters. The self-priming pump also ensures a stable operation as is it able to lift liquid from below the inlet level and can handle a mix of air and liquid until the pump reaches a fully-primed pumping condition.

The JP 5-48 PT-V booster set has built-in thermal protection, which immediately stops the pump if it overheats. The motor is air cooled and equipped with oversized, sealed, greased-for-life ball bearings to ensure silent operation and minimum service.
