Every unplanned maintenance shutdown of your mining production line costs you substantial money per hour. When your crew has to work overnight to replace worn parts, you are not only stuck with troublesome handling of abrasive slurry but also facing wrong slurry pump selection.

Standard iron pumps get corroded within days when exposed to highly abrasive mine tailings. As an experienced manufacturer of mining pumps, we fully understand that reliable service under such harsh operating conditions hinges on two core factors:

• Hardness Matching: Avoid settling for ordinary iron impellers. For sharp, heavy solid particles, high-hardness chrome alloy impellers (specifically Cr27/A05 with hardness ranging from 58 to 62 HRC) are required. This hardness threshold marks the turning point where the metal stops rapid abrasion and effectively resists erosion from rock fragments.

• Rotational Speed and Wear: Excessively high pump speed triggers severe internal turbulence. By reducing pump rotation speed, deploying heavy-duty slurry pumps with moderately higher power ratings and operating them near the Best Efficiency Point (BEP), you can instantly double the service life of all wet-end components.

Runheng Machinery does not merely supply off-the-shelf standard pumps. We engineer robust, long-lasting heavy-duty pumping systems tailored to your specific Specific Gravity (SG) and d50 particle size.
