Weir Minerals Africa says its locally manufactured Warman ® WBH® range of pumps provide access to the latest slurry pumping technology, helping ensure productivity demands are met.

Typically used in heavy duty applications such as mill discharge, slurry transfer and process pumping applications, the Warman WBH is suitable for both greenfields and brownfields installations, according to the company.

With a “revolutionary” one-piece frame for correct alignment of bearings, seal and impeller to front liner, the Warman WBH is engineered for enhanced efficiency and operational savings in mind, the company says. “The pump incorporates a fully-adjustable and rotatable throatbush to more evenly spread the wear and maintain the pump’s performance for longer periods.”

The ‘One Point’ front liner adjustment feature allows both rotation and axial movement to minimise front impeller gap to reduce wear and maintain performance. “Significantly, this adjustment can be made while the pump is running, eliminating the need to stop production resulting in cost savings for the plant,” Weir says.

The company continued: “The streamlined impeller inlet of the Warman WBH pump facilitates enhanced handling of even the most difficult slurries. While the low-flow gland seal, expeller seal and mechanical seal options on the pump mean there is less dilution of the slurry and lower required flow of gland water.”

Equipped with large capacity bearings, the pump can withstand high loads without affecting bearing life, according to the company. “The impeller and volute flow paths are streamlined to enhance efficiencies and extend component wear life,” Weir says.
