Product Overview
The Grundfos JP 4-47 is a self-priming jet pump designed for domestic water supply, garden irrigation, and water transfer applications. With strong suction capability, it is ideal for drawing water from wells, ground tanks, and below-ground sources where the pump is installed above the water level.
The pump is constructed with a stainless steel housing (AISI 304) and a composite impeller (PPO-20GF), providing excellent corrosion resistance and durability. The integrated ejector with guide vanes ensures efficient self-priming performance and stable operation, even when handling air-liquid mixtures during the priming phase.
According to the performance data, the pump operates at a rated flow of 4 m³/h with a corresponding head of 41 metres. It achieves a maximum head of 44.5 metres at shut-off conditions. Based on the performance curve, the pump delivers practical flow across typical domestic pressure ranges and supports a suction lift of up to 8 metres.
The unit is powered by a 0.56 kW electric motor operating on a 1 x 240 V, 50 Hz supply, with a rated current of 3.8 Amps. It includes built-in thermal protection to prevent overheating and features sealed, grease-for-life ball bearings for quiet and maintenance-free operation.
