Dimensionally interchangeable with Warman® AH / AH(R). Matec pumps are manufactured as independent aftermarket replacements and are not affiliated with Weir Minerals.
MHM (metal-lined): A05 / A07 high-chrome wet end. Best for coarse, high-density, high-impact abrasive slurries such as mill discharge and cyclone feed. MHR (rubber-lined): Natural rubber R55 / R26 liners. Best for fine, corrosive, low-specific-gravity slurries where elastomeric wear resistance outlasts metal.
The Matec MHM is a heavy-duty horizontal centrifugal slurry pump built for the most abrasive mining duties. It is dimensionally interchangeable with the Warman® AH series and is the metal-lined standard for coarse, high-density slurries.
The Matec MHR is the rubber-lined counterpart of the MHM, dimensionally interchangeable with the Warman® AHR series. Its elastomer wet end is optimised for corrosive or fine-particle duties where rubber delivers longer wear life than high-chrome.
Applications: Mill discharge and cyclone feed in concentrators, Tailings transfer and thickener underflow, Primary sand and coarse solids pumping, High-density abrasive slurries in copper, iron and gold processing.
Applications: Acidic or corrosive tailings and process water, Fine coal, phosphate and kaolin slurries, Flotation and leaching circuits with low pH, Fine-solids transfer where impact is low but corrosion is high.
