View Detail


The Variboost 3-60+ has been designed for supplying boosted cold water to houses and apartments that require increased water pressure. The Variboost 3-60+ is fitted with a variable speed drive that will give a constant pressure against a variable flow.


The pumps used for the Variboost 3-60+ are horizontal multistage with a stainless steel casing and the unit is best suited on systems with unvented hot water cylinders and bathrooms with mixer taps.


It varies its speed as the demand increases and decreases in the system. The inverter can be adjusted to give the required system pressure. 


The two main advantages over standard fixed speed systems is the energy saving and the reduction of pressure fluctuation. The inverter also has a dry running device that stops the pump if the break tank was to run dry. Each unit is fully tested before going to site which makes it a complete ‘’plugin and play’’ booster system.


PUK-VARIBOOST 3-60+ with a duty of 1l/s @ 3 Bar. 0.75Kw

Each pump is installed on a steel base frame and is fitted with pressure gauge, pressure vessel and suction and discharge valves.


The unit should be installed next to an adequately sized break tank and the suction line should flood the pump. We would not recommend the pump to be used on a suction lift or to pump hot water.

  • Power Supply: 230v Single Phase.
  • Pipework size: Suction 1” BSPM. Discharge 1” BSPM
  • Pressure Vessel: 5lit.

Motor Sound

  • 65db at 1m from the pump during operation.
  • 74db at pump during operation. 

*The unit should not be installed outside and should not be connected directly off the mains water supply. The unit is not entirely silent and should be installed in a location that is not going to cause disturbance.*
