Knowsley SK were approached by a leading international fuel storage Company to design, manufacture and supply a mobile firefighting foam pump and proportioning system that can be used to provide protection for tanks and other equipment at their UK Tank Farm.

Knowsley engineers worked closely with our client to ensure that their specific requirements were incorporated into the trailer design prior to manufacture.


The trailer was designed to incorporate a Turbinator Midi water driven foam proportioner with an operating flow rate between 500 and 3,000 l/min at pressures up to 16 bar. The Turbinator was fitted with 6” Storz fittings for quick connection at high flows and a removable inlet/outlet breeching with 4no valved 2.5” instantaneous fittings.

The trailer accommodates a standard IBC of foam concentrate and proportions the foam concentrate at 1%. Additional fittings were provided to allow the operator to introduce further external foam supplies if required.

A Quenchor water monitor is installed at the rear of the trailer with an option to use with foam or water to provide further options to cool or provide a foam blanket onto a spill fire.
