The Grundfos JP 4-54 PM1 is an automatic pressure jet pump system designed for tank filling, garden irrigation, and household water transfer applications. The system combines a Grundfos JP self-priming pump with a PM1 pressure manager, providing automatic start and stop operation based on water demand.
The pump is constructed with a stainless steel housing (AISI 304) and a composite impeller (PPO-20GF), ensuring corrosion resistance and long service life. The integrated ejector enables efficient self-priming and allows the pump to handle air-liquid mixtures during priming for stable operation.
According to the technical data, the pump operates at a rated flow of 4 m³/h with a corresponding head of 46 metres. From the performance curve, the unit achieves a maximum head of approximately 50 metres at shut-off conditions and delivers practical usable flow across domestic pressure ranges. The system supports a suction lift of up to 8 metres.
The unit is powered by a 0.75 kW electric motor operating on a 1 x 230 V, 50 Hz supply, with a rated current of 5.1 Amps. The PM1 controller starts the pump at 1.5 bar and keeps it running as long as there is flow. It includes dry-run protection, anti-cycling functionality, and an integrated non-return valve for reliable and safe operation.
