Trusted Quality in Every Component

The Grundfos pump is an all-in-one compact water boosting system that is designed for domestic water supply and other boosting or lifting applications. This multi-stage centrifugal pump can self-prime from a well depth of down to 25 feet within a maximum time of 5 minutes. Also, it is easy to operate and completely user friendly. The setting modes such as pump on, auto reset, and alarm are clearly displayed with an indicator light. A pressure switch and a pressure tank are built into the systems to ensure that water is readily available from the tap. When water is required, the pump automatically starts and no loss of pressure will be felt. You do not need to worry about any other separate items.

In addition, the pump incorporates an electronic protective function which will automatically stop the unit when the pump runs dry. And, the pump is cooled by the pumped water which eliminates the need for a chambersome noisy cooling fan. This is a great space-saving feature and allows the unit to be installed for domestic applications where low noise is a major consideration. Because the pump is made from weatherproof, corrosion-resistant materials, it can even be placed outdoors. The installation is extremely easy and can be done in a matter of minutes.

Design to meet the needs:

  • Water supply from wells
  • In private homes and weekend cottages
  • On farms or in market gardens
  • Delivers more power and faster water in your shower fixtures
  • Higher delivery pressure to support multiple fixtures
  • Rinse off in the shower when someone uses the bathroom faucet
  • Improves all water using home appliances operates

High Performance System Components

User-friendly

Control Panel

Control panel with indicator lights of actual setting - Pump on, auto reset and alarm (dry-running or overheating.)

Thermal Protection

If the pump overheats, it immediately stops and then automatically restarts after the cooling down period.

Dry-run Protection

If the pump runs dry, the pump automatically stops. It will then attempt to restart every half hour for a maximum of 24 hours.

Flow Switch

Enables the system to automatically stop the pump during normal operation when flow drops below 0.3 gpm, or shut off in 12-15 seconds after flow stops.

Built-in Check Valve

Incorporates a check valve which prevents backflow during priming and operation.

Built-in Pressure Tank

A small 5 oz. built-in pressure tank, ensure the water is readily available from the tap and minimize motor startup and stop.

Drain Plug

Drain the water out of the pump as the near freezing water begins to expand, which prevents the pump from freezing and becoming damaged during the winter season.

Anti-Cycling Features

Prevents the pump from continuously starting and stopping when you have a dripping tap or minor leak in the system.

Easy to Install

The outlet pipe connection can be angled up to 5° to fit your existing pipework. Also, the compact design makes the pump easy to place indoors and outdoors where space is limited.

Easy to Operate

Operates entirely by means of the control panel with just one simple touch button.

Quiet Operation

The pump is cooled by the pumped water which eliminates the need for a noisy cooling fan.
