Designed for hard rock grinding mill applications
The UMD pump is designed specifically to handle the exceptionally abrasive discharge slurries that flow from hard rock grinding mills. It’s heavy-duty design features a unique unlined casing design, optimized impeller, and oversized liners, as well as our unique wear ring assembly:
- A large clearance around the impeller creates a deep bed of slurry between the impeller and casing, which acts as a buffer and shields the casing from direct impact of coarse solids. In addition, a large cutwater reduces turbulence to extend pump life.
- The shape of the pumping vanes has been optimised with increased shroud diameter and improved expelling vanes. This advanced design limits localised wear on the leading edges to maintain pumping efficiency and extend wear life.
- Oversized suction and backliners – which are available in a range of materials – protect the sides of the casing from wear due to turbulence.
- The unlined casing design reduces space requirements, as well as maintenance time (by at least 20%) and costs (as fewer components are required). The symmetrical design means that the same casing, suction and backliners, and wear ring can be used for both left- and right-handed orientations, reducing inventory requirements.
