WARMAN® mill circuit pumps (MCR²®, MCR®, MCR®-M, MCU®)

Able to process large particles in highly abrasive slurries, WARMAN® mill circuit (MC) pumps are specifically designed for severe mill circuit duties and aggressive slurry applications (Service Class 3 & 4). 

These types of horizontal centrifugal slurry pumps are renowned for their performance with ball and SAG mill discharge and cyclone feed applications in mineral processing plants. Today, the WARMAN® MCR²® mill duty pump represents the latest generation of this technology leadership, extending the performance, wear life and reliability that have made WARMAN® MC pump series the industry benchmark.

Compared to other mill circuit pumps, WARMAN® MC pumps offer the following benefits:

• Hydraulics are based on more than 30 years of fundamental and applied research including various wear performance field trials
• Superior reliability, performance and wear life due to their advanced hypereutectic alloy and elastomer technology, unique design and wear evaluation software
• A flexible design that comes in a variety of sizes and has lined or unlined options available
• Large, open internal passages and expelling vanes that improve flow within the pump and reduce internal velocities and wear
• Features a reversible casing (open back design) that allows the discharge orientation to be positioned either right vertical (standard Clock Wise - CW) or left vertical (Counter Clock Wise - CCW) providing greater layout flexibility
• The two-piece cover plate provides easy access to the pump internals for replacement of the impeller and throatbush
• The low flow design stuffing box improves packing life and decreases gland seal water consumption by up to 50%
• Their quick wet-end change-out helps to reduce mill downtime
• Made with the latest wear-resistant material technology which results in increased pump wear life

In addition to the above, WARMAN® mill pumps feature:

• A large-diameter, low-speed, high-efficiency impeller, manufactured from a wide range of abrasion-resistant alloys
• Heavy-duty roller bearings housed in a low-profile fixed assembly (or a removable bearing cartridge)
• Patented shrouds that extend past the periphery of the impeller
• Increased throatbush adjustment with the WARMAN® XA throatbush
