Key Features

Automatic Pressure Switch

Starts and stops on demand — activates when a tap opens, shuts off when pressure is restored.

No manual priming needed. Draws water from source automatically from first use.

Over-Pressure & Overheat Protection

Built-in safety cut-offs protect the motor and pump from damage in fault conditions.

Run Dry Safe

Can operate dry for up to 30 minutes without damage — ideal for intermittent systems.

Low Noise Operation

Quiet diaphragm mechanism — suitable for cabins, caravans, and living spaces.

4-Chamber Diaphragm

Smooth, steady flow with reduced pulsation vs single or dual-chamber designs.
