FEATURES & BENEFITS

• Self-priming, featuring a suction lift of up to 8 m
• 1" (25mm) Suction and Discharge
• Automatic start/stop according to consumption
• Controlled pressure for the comfort of constant water supply without pressure drops
• Fewer starts and stops in case of low water consumption or leakage loss
• Robust design and corrosion-free materials for a long lifetime.

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.

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.
