he Grundfos JP4-47 is a compact, self-priming, single-stage centrifugal jet pump designed for reliable and trouble-free water supply. With excellent suction capacity and a built-in ejector with guide vanes, the JP4-47 provides optimum self-priming performance with a suction lift of up to 8 metres.

The robust design features a stainless steel pump housing, composite impeller and electrophoretic paint coating, providing excellent corrosion resistance and long service life. Its compact size and convenient lifting handle make the pump easy to carry, handle and install.

The JP4-47 can lift water from below the inlet level and is capable of handling a mixture of air and water until the pump reaches a fully primed pumping condition. Built-in thermal and current protection automatically stops the pump if it overheats, while the air-cooled motor and sealed, greased-for-life ball bearings provide quiet operation and minimal maintenance.
