The Grundfos JP-A, JP-D and JP-AD are self-priming, single-stage centrifugal pumps that feature an axial suction port and a radial discharge port. The pumps have a built-in ejector with guide vanes for optimum self-priming properties.

Jet pumps are available in two material variants.

Material variant A: Cover plate, motor stool and base plate in one unit. The handle is fitted crosswise. Both elements are made of composite material.

Material variant B: Stainless steel cover plate, aluminium motor stool and stainless steel base plate, all separate parts.

When used in combination with a pressure control or tank, Grundfos jet pumps are ideal for small water supply systems.
