Slurry Pumps and Valves
Wear-Resistant Rubber Slurry Pump
The wear-resistant rubber slurry pump moves abrasive mineral slurries through wet-end circuits in concentrator plants. It is typically installed where slurry must be lifted, transferred between process units, or fed to hydrocyclones, filters, and thickeners.
Technical parameters
The pump casing and impeller are lined with natural rubber that absorbs particle impact and resists cutting wear. This lining extends service life in medium-duty slurry-transfer and sump-pumping applications.
Each model code shows nominal suction and discharge diameters. Larger frame numbers correspond to pumps designed for higher flow and head. Use the table to compare hydraulic performance across the range and identify the model that fits your circuit's duty point.

Standard-model catalogue figures. Actual capacity, power draw and wear life shift with ore properties, feed gradation and circuit conditions. Use them to shortlist, then confirm the duty by testwork, flowsheet calculation and a written confirmation from the manufacturer.
What decides the selection
Before selecting a pump, define the slurry’s solids concentration, particle size distribution, and specific gravity. Confirm the required flow rate and total dynamic head at the installation point. Account for pipe friction losses, static lift, and any corrosive or temperature effects that may influence lining and seal material choice.
