Replacement Pump Head H3 20/4

The W2 Series household booster pump is designed with a built-in check valve within the pump casing and features an automatic programme that enables the pump to operate in start/stop mode. This effectively boosts water pressure for showers, taps, and other plumbing points in your home.

The W2 Series epoxy-coated volute pumps offer two operational modes:

- Manual Mode: The pump operates at a constant shaft rotation speed and stays on until manually switched off.

 - AUTO Mode: The automatic programme activates when a tap is opened and deactivates when the tap is closed, responding automatically to changes in flow rate and pressure.

A check valve is integrated into the pump body. The automation, triggered by a single button press, controls the pump in start/stop mode based on water flow and pressure. We recommend using these pumps in conjunction with tanks from which they draw drinking water to supply consumers.

ELECTRICAL AND THERMAL PROTECTION: These safety systems prevent pump breakdown due to external factors unrelated to the pump's operation.
