Product Overview
The Grundfos JP 3-42 PT-V is an automatic pressure jet pump system designed for home water supply, garden irrigation, and light water transfer applications. The system includes a Grundfos JP self-priming pump, a pressure switch, pressure gauge, and a vertical diaphragm pressure tank, delivering stable and automatic pressure control.
The integrated pressure tank reduces water hammer in the pipeline and minimizes pump cycling by supplying stored water during low demand conditions. The pressure switch and tank work together to ensure efficient start and stop operation, improving system performance and extending pump life.
The pump is constructed with a stainless steel housing (AISI 304) and a composite impeller (PPO-20GF), ensuring corrosion resistance and durability. The self-priming design allows the pump to handle air-liquid mixtures during start-up and supports suction lift from below-ground water sources.
According to the technical data, the pump operates at a rated flow of 3 m³/h with a corresponding head of 36.5 metres. From the performance curve, the unit achieves a maximum head of approximately 42 metres at shut-off conditions and supports a suction lift of up to 8 metres.
The unit is powered by a 0.45 kW electric motor operating on a 1 x 240 V, 50 Hz supply, with a rated current of 3.1 Amps. The pressure switch is preset with a cut-in pressure of 2.2 bar, ensuring reliable automatic operation based on system demand.
