Submersible pump specialist ITT Flygt has added a range of stainless steel pumps for applications in corrosive and abrasive environments, for example mines, industries and public utilities. The new product range consists of both drainage and solids handling pumps. They are especially designed for pumping applications with a pH range of 2-10, this means environments where acid or alkaline liquids have to be handled.
ITT Flygt's corrosion-resistant pumps in the new 2700 range are designed to be extremely wear resistant, robust and easy to handle and maintain.
The pump range consists of three drainage pumps and three solids handling pumps, all available for 50 or 60Hz.
Typical applications are acid mine drainage, wash water sumps in pickling bath processes in the steel industry, pH-neutralisation of the wet scrubber process in the steel and power industries, and utility drainage on landfill sites.
Ordinary submersible pumps are designed to be used in the pH range 5-8,Our new stainless steel pumps have been developed and successfully tested for pumping liquids, sludge and suspensions in extremely tough and demanding environments.
The new 2700 pump range offers flexible and cost-effective dewatering solutions where, for example, cast iron or aluminium pumps could lead to limited life time because of corrosion, chemical attacks or low abrasion resistance, says Michael Hjelm, Business development manager at ITT Flygt in Stockholm, Sweden.
The robust and uniform pump design incorporates a maximum of standardised components, which facilitates and lowers cost for maintenance.
For example, the pumps in the 2700 range have double mechanical shaft seals, where the same shaft seal fits all pumps in the range.
The pumps outer housing is impact-resistant, making the pumps suitable for operation in tough environments.
A slim pump profile enables easier installation in confined spaces and into pipes.
A ring-shaped handle gives good manoeuvrability during installation, and serves as a stand when the pump is inverted for service.
Furthermore, the drainage pumps can easily be converted from high head version to normal head version.
The first product to be introduced is the largest drainage pump 2750, the other models in the 2700 series will be available successively.
