Alarm Valve Booster Pumps

Alarm Valve Booster Pumps

We manufacture a range of Alarm Valve (or False Alarm, or Towns Main) Booster Pumps for sprinkler systems that are fed from the mains water supply.

This compact unit (just 600 x 400mm) automatically boosts the mains pressure when required, controlling pressure fluctuations in conjunction with the accumulator, thus preventing false trips of the alarm valve.

The alarm valve booster pump is fitted as standard with an 8-litre accumulator, designed to prolong the life of the pump by eliminating unnecessary motor stops/starts, and allowing the pump an extended run when the cut-in pressure is achieved. The pump will not affect a sprinkler system live activation due to its low flow characteristics and the use of an on-delay timer.

All units are designed to comply with LPC guidelines, and are fully set and tested prior to dispatch.

Key Features

  • Pump producing e.g. 13 lpm@3 bar.
  • On-delay timer (400v models must have neutral for a 230v supply) to limit the number of pump starts, prolonging its life, preventing overheating and preventing counteraction of a live sprinkler event.
  • Bailey & Mackey 1381v pressure switch, 14 or 28 bar.
  • Starter with thermal overload and >1m flex.
  • Filtered Inlet valve, gate outlet and test valves included; all ½” connections.
  • Spring check valve to prevent backflow.
  • Glycerine filled pressure gauge with no loss connector.
  • Corrosion-free polypropylene board, Unistrut frame for direct wall mounting.
