Ciba Speciality Chemicals (Bradford, West Yorkshire, UK) has selected a Hidrostal diesel-driven pump set for transferring waste and fire water. In an environment with a high risk of fire, it is essential to have pumping equipment that can handle waste resulting from a mixture of fire water, chemical and other materials. To avoid any highway flooding and environmental contamination in the time of fire, Ciba required a pumping solution that could operate without electricity and could pump firewater back to the storage/treatment works. The Hidrostal screw centrifugal impeller enables blockage- and damage-free handling of delicate crystals, viscous products, effluents and other materials. The low shear design of the impeller allows pumping with minimum agitation and hence minimal emulsification so resolving the problem of pumping fire water and chemical mixtures. The pumps are also available in a wide range of corrosion- and abrasion-resistant materials.
