ITT Corporation (NYSE: ITT) announced the launch of the new Goulds XHD Extra Heavy Duty Slurry Pump (Fig. 1), a next-generation product that can handle the heaviest slurry under the toughest conditions. The Goulds XHD is designed for use in mining and related industries, including applications involving primary metals, mineral processing, non-metallic mining, power utilities, and sand and aggregates. The XHD pump is designed to work optimally on both Service Class III (heavy – including thickener underflow, tailings disposal, slurry transfer and dilute media) and Class IV (very heavy – including primary grinding circuits, heavy media, thickener underflow and tailings disposal) slurries as defined by the “Hydraulic Institute”. The pump is available in six discharge sizes ranging from 80 mm (3 inches) to 300 mm (12 inches), in four power frames and configurations tailored to operator needs. The capacity range of the XHD pump is 2950 m³/h (13 000 gallons/min.) with discharge pressure to 85 m (280 feet).
Built with double-wall construction, the XHD pump features a full metric design and a large-diameter closed impeller, which extends wear life by enabling lower RPM operation. Using the latest computational fluid dynamics (CFD) technology, ITT Goulds Pumps engineers designed the XHD pump for optimal hydraulic operation – resulting in higher efficiency, longer wear and lower power consumption. Early XHD users have reported drops in electrical consumption of 10-15 % over previously installed pumps. To meet the demands of a variety of slurry applications, users may choose from a selection of HC600 replaceable chrome iron liners that optimize their use of the XHD pump and extend its wear life. The unit’s precision-machined, compact frame contributes to accurate alignment and provides rigid, vibration-free support. Safe, simple lift points on the XHD pump enable easier component assembly and installation, and its flanges are designed to suit both ANSI and DIN metric standards.
The XHD pump is also relatively easy to install, without changing piping configurations or process design. A low center-line height and the wet-end design allow the XHD pump to be adapted to the foundations of currently installed slurry pumps from ITT Goulds Pumps or other manufacturers.
Five of the pump’s standard features are patented or have patents pending, noted John Manna, vice president of global marketing for ITT Goulds Pumps. “The mining industry has seen dramatic improvements in extracting and crushing methods, and now this new pump provides that same leap in productivity for moving slurry,” Manna said. The new pump is designed to be maintained even while running, and to require less downtime for service procedures – with parts that are more accessible and adjustable than in other slurry pumps. The pump’s short bearing housing is easily adaptable to nearly any existing foundation, so operators can retrofit existing pumps without investing in costly refitting of pipes, electrical lines and concrete base structures.
