SD80 and SD120 Fire Sprinkler Pump Units

Residential and Domestic Sprinkler Systems


The SD120 and the SD80 are designed for residential and domestic use to BS9251:2014. 

With the introduction of sprinkler systems in domestic buildings properties may have insufficient water pressure in the towns main to meet the requirements of the sprinkler system.  The SD120 and SD80 connect directly to the town’s main and are designed to maximise the water supply available by enhancing the existing available pressure. Due to it's intelligent control system the SD unit will not create a negative pressure in the town’s main and avoids the necessity for water storage tanks.   The SD range of fire pumps are the only units that meet the requirements of the UK Water Protocol that can be connected directly to the town's main water supply.
