Flomate Mains Boost - Low water pressure pump

Previous Products

Now available as MBF 12

Suitable for low occupancy properties with typically one bathroom.  Flomate Mains Boost pump is designed to be connected directly to the incoming mains and will deliver an additional 1.5 bar pressure to the existing mains pressure and a maximum flow rate of 12 litres minute.

The pump will start automatically when a flow rate of 0.6 litres per minute or more exists.

The pump also features a built-in bypass, meaning that when the mains pressure exceeds 1.5 bar, the additional performance is not restricted.


  • At times when there is insufficient mains water pressure Flomate is designed to ensure that the pump will deliver an additional 1.5 bar to any existing mains pressure at a maximum flow rate of 12 l/min
