Full product specification details can be found on the comprehensive product sheet available for download from our website.


Pillar style hydrants allow large volumes of water to be accessed rapidly making them an extremely popular addition to many land-based applications. The range of Knowsley SK pillar hydrants encompasses models that have been designed to withstand a variety of environmental conditions, such as our dry-barrel hydrants, which are suited to sub-zero conditions as their self-draining nature eliminates the frost damage associated with wet-barrel hydrants. We manufacture hydrants in cast iron, steel and low temperature steel allowing customers to choose the most suitable option for their requirements, as well as offering a choice of outlet configurations and below ground dimensions.


Over the course of 75 years, Knowsley SK has developed its knowledge, skills and expertise in the design and manufacture of a range of monitors for various fire fighting applications.  This range includes fixed, oscillating, mobile and portable units, all of which afford unsurpassed performance levels. The Evictor is a fine example of our development capabilities and the variety of models available.  This self-oscillating monitor was designed to provide absolute protection against vessel attacks by pirates, and unattended operation negates the requirement for a crew member to be present. Full details of this and our other monitors can be found on our website.


Our range of hand-held nozzles has been designed to affix onto hose lines in order to provide ultimate control, power and precision whatever fire fighting scenario you come up against.  Knowsley SK is pleased to offer several different designs of nozzle in order to meet the varying requirements of different applications. Our most recent addition to our nozzle range is the Striker 10, an FM approved combination nozzle that allows a choice of three flow positions: straight jet, atomised spray or wide-spreading cone. This is also accompanied by three separate flow rates allowing the operator maximum control.

Knowsley SK’s Turbinator is a positive displacement foam concentrate dosing machine that has been manufactured from high-grade materials allowing it to withstand the most severe conditions.  It uses either freshwater or seawater as its source and is totally unique in its nature in that it does not produce any waste water.  It requires no external power source, making it just as suited to mobile applications as within fixed systems, and there is a choice of three sizes available, each of which offers different flow ranges – MIDI 500-3000 l/min, MIDI-PLUS 1000-6500 l/m, MAXI 1500-12000 l/m.
