JP PT Booster

Grundfos JP PT Boosters provide the comfort of constant water pressure with automatic start and stop controlled by a pressure switch and pressure tank combined. The pressure tank limits the number of starts and stops, as water stored in the tank can be used without starting the pump in case of low water
consumption or leakage loss.

JP PT consists of a Grundfos JP pump, a pressure switch, a pressure tank and a pressure gauge.

JP pump is a self-priming, single-stage centrifugal jet pump. The jet pump has
excellent suction capacity and is designed for long and trouble-free operation.
The built-in ejector with guide vanes ensures optimum self-priming properties.


The boosters are suitable for domestic water supply, where pressure boosting and self-priming is needed.
