Grundfos-JP Booster self-priming pump

Overview

Grundfos_JP_BoosterThe Grundfos JP pump is a self-priming, single-stage centrifugal pump with axial suction port and radial discharge port, G 1 or Rp 1. The pump has a built-in ejector with guide vanes for optimum self-priming properties.

JP 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.

The robust design makes the pump suitable for fixed installation. The custom-built composite handle is fitted lengthwise.

The pump is directly coupled to a special fan-cooled asynchronous Grundfos motor that is adapted to the pump performance Single-phase motors have a built-in thermal switch and require no additional motor protection Three-phase motors require external motor protection

Applications

Built for a long, trouble-free working life, the small and handy Grundfos jet pump is suitable for a wide variety of water supply and transfer duties in home, garden and hobby applications as well as in agriculture, horticulture and small-scale service industries.

When used in combination with a pressure control or tank, the JP pump is ideal for small water supply systems.

Features and benefits

  • Grundfos JP booster dimSelf-priming
  • Stable operation even if there is air in the liquid
  • Ideal for small water supply systems
  • Compact and handy
