The Grundfos JP Jet Pump Range

The Grundfos JP range consists of robust, self-priming, single-stage centrifugal jet pumps designed for domestic water supply, garden irrigation, and pressure boosting. Featuring stainless steel housing and excellent suction lift (up to 8m), they are ideal for moving water from rainwater tanks or wells.

Key Features and Models

• Models: Common models include the JP 3-42, JP 4-47, JP 4-54, and JP 5-48.
• Construction: High-quality corrosion-resistant materials (stainless steel pump housing) ensure long life, often over 15 years with proper maintenance.
• Performance: Designed to deliver a steady flow and pressure (30–50 PSI).
• Versatility: Suitable for shallow wells, with high suction capability.
• Self Priming: Designed to have excellent suction lift capabilities, the Grundfos Jet Pump is able to draw water up to 8 metres vertically from below the level of the pump. This makes it perfect for pumping water from below ground tanks, dams and shallow wells.
• Robust Inside & Out: Excellent corrosion resistance is ensured inside and out with a stainless steel pump housing and composite impeller material.

Typical Applications

• Domestic water supply (rainwater tanks).
• Garden and lawn irrigation.
• Pressure boosting for showers and household taps

The Grundfos Jet Pump range comprises of three configurations,

- JP (PUMP ONLY) For basic applications that require simple on/off functionality.

- JP PT The addition of a pressure tank greatly reduces the number of pump stop/starts in order to maintain household tap pressure, resulting in quieter nights and reduced power consumption.

- JP PM The Pressure Manager (PM) controller automatically stops and starts the pump in line with household demand. In addition, the device prevents the pump from continuing to run if the water source runs dry. The PM also provides a cycling alarm, preventing the pump from rapidly turning on and off when there is a leaking pipe or dripping tap.

Common JP Range Models

• JP3-42 : 0.45 kW, suitable for 2-3 taps.
• JP4-47: 0.56 kW, suitable for 3-4 taps.
• JP4-54: 0.75 kW, suitable for 3-4 taps.
• JP5-48: 1.01 kW, suitable for 4-5 taps.

These pumps operate with high efficiency and are designed to provide reliable service in both indoor and outdoor environments.
