PUK VARI TWIN - Domestic/Commercial Booster

The PUK VARI TWIN cold water booster set has been designed as a cost-effective solution for small commercial applications and large residential properties. It is very similar to the PUK VARI BOOST but with an extra pump for increased performance and reliability.

It is built from WRAS approved stainless steel pumps (with pressure vessels) and stainless manifolds with a common control panel connected to a pair of high-quality inverters. Both manifolds exit at the front and can be connected from either side allowing for easy installations.

We can also supply the PUK VARI TWIN anti-vibration mounts and flexible connectors. Call 01322 292 415 to discuss your requirements.

Our Booster Pumps Sets are Made in Britain

We have always been proud to say that our booster pump sets have been built in our workshop in Rochester (Kent, UK) by our skilled engineers. To assure customers of this we recently applied for ‘Made in Britain’ mark approval and will proudly show this mark on all of our PUK Products going forward.

High Performance & Energy Efficiency

The PUK VARI TWIN is capable of a wide range of duties and can be tailored to offer the highest efficiency and produce energy savings over older pumps.

The PUK VARI TWIN is smart and can be customised to suit your needs in a variety of ways. As standard, the one pump is usually all that is needed but the panel can alternate between both pumps to even wear, prolong life and save energy. For more power, both pumps can run at the same time and double the flow.

Inverter Driven Pump Control

Each pump is controlled to give a constant pressure and will ramp up speed when the demand increases in the building. This type of control will give clients savings on energy and reduce the risks of pressure problems in the systems pipework.

  • Built-In LCD Display
  • Status Notifications
  • Alarm Notifications
  • Switch loads across pumps (equal load/wear)

Each inverter has a simple interface that is easy to understand and we stock them in our Rochester warehouse for fast replacement should the unlikely need for replacement arise.
