HM/MM Slurry Pumps

Key Features & Benefits of HM/MM Slurry Pumps

Unmatched Reliability in Operation
Specially developed features ensure trouble-free operation and minimized downtime, maximizing cost-effectiveness.

• Robust Bearing Assembly: An oversized, high-strength alloy steel shaft is supported by heavy-duty, grease-lubricated taper roller bearings in a self-contained cartridge for maximum durability.

• Advanced Sealing Options: A double seal arrangement protects bearings from contamination. Customers can choose from proven, reliable sealing methods, including expellers, flushed glands, or mechanical seals, to meet specific operational needs.

• Modular & Back Pull-Out Design: Full interchangeability of parts reduces inventory costs. The back pull-out feature allows for easy inspection and maintenance without disturbing the pump casing or piping.

• Quality Assured: All pumps and parts are manufactured under a total quality management system in ISO-certified production units.

Product Ranges: Tailored to Specific Demands

HM Range (Heavy Duty)

Ideal for extreme abrasion and high-head applications (e.g., hydrocyclone feed, mine tailings).

• Model Lineup: HM50 to HM300 (inlet sizes: 50 mm/2” to 300 mm/12”; outlet sizes: 32 mm/1.5” to 250 mm/10”).

• Weight: 136 kg/300 lbs (HM50, single adjustment) to 2,850 kg/6,283 lbs (HM300, double adjustment).

• Configurations: Hard metal (HM) for maximum abrasion resistance; rubber-lined (HR) for enhanced corrosion protection.

MM Range (Mining Duty)

Optimized for high-flow, moderate-head tasks (e.g., in-plant slurry transfer, coal and power plant ash handling).

• Model Lineup: MM100 to MM500 (inlet sizes: 100 mm/4” to 500 mm/20”; outlet sizes: 75 mm/3” to 450 mm/18”).

• Weight: 170 kg/375 lbs (MM100, single adjustment) to 8,030 kg/17,703 lbs (MR500, single adjustment).

• Configurations: Hard metal (MM) for heavy-duty use; rubber-lined (MR) for gentle handling of less aggressive slurries.

• Special Option: Available with fully recessed induced vortex impellers for handling large solids.

Optimized for Long Wear Life
These pumps are built to last, with designs and materials focused on extending service life in harsh conditions.

• Premium Wear Materials: Wear parts are constructed from the highest quality hard metal, rubber, and corrosion-resistant materials.

• Robust Design: Extra-thick sections are used at known points of wear to withstand abrasive slurries.

• Interchangeable Parts: Hard metal and elastomer parts are fully interchangeable, allowing for the optimal material selection for each specific application.

• Wear Clearance Adjustment: An optional double adjustment feature allows for the precise setting of both front and back impeller clearances, restoring pump performance and significantly increasing wear life without disassembly.

Low Power Consumption
Efficiency is engineered into every aspect of the hydraulic design to reduce operating costs.

• High-Efficiency Hydraulics: Advanced fluid dynamic software and 3-D computer design technology are used to develop optimal pump hydraulics.

• Operation at Best Efficiency Point: Range optimization ensures the pump operates close to its best efficiency point, ensuring even wear and minimal energy usage.
