Pump and tank fire sprinkler systems systems ensure a reliable water supply for fire suppression in large buildings and in areas with insufficient or unreliable mains water pressure.

Pump systems, typically powered by electric or diesel engines, play a key role in maintaining water pressure during fire emergencies. In the UK, they are often installed in larger commercial and industrial buildings where the water demand exceeds what the mains can provide. Diesel-driven pumps are particularly favoured for their reliability in power outages, a consideration in British fire safety regulations.

Tanks for water storage are required when the mains supply is insufficient to meet the sprinkler system’s flow and pressure requirements. British standards dictate that tanks must be sized to provide a specific duration of water supply, typically 30, 60, or 90 minutes, depending on the building’s risk category.

Pump and tank sprinkler systems ensure robust fire safety compliance, protecting lives, property, and meeting insurance and regulatory requirements effectively. Regular testing and maintenance are essential to their operational reliability.
