The PUK Variboost 3-120 is a variable speed constant pressure booster pump that has been designed to suit systems that have unvented hot water cylinders with pressure reducing valves and high resistance bathroom fittings that require a balanced pressure on hot and cold supply pipes.

The Variboost 3-120 has an inverter designed for water boosting applications with dry running protection. The units have a 19lit. WRAS approved pressure vessel which allows for smooth cut in and ramp down of the pump. The pumps are WRAS approved and will suit potable water applications.

We can offer a pre-commission of the unit so that the installation is made a simple as possible. All that is require is the connections of the pipework and power supply and the pressing of the start button.

The pump should be connected to an adequately sized break tank so that the out let flow rate will not drain the tank when the system is a full flow. To give a 5 minute storage time the minimum size for the tanks is 600lit. (Suggested Size 750lit).
