FLS millMax Pumps

Key Innovations: Why Choose millMAX?

Proprietary Wear Ring Suction-Side Sealing

• Dual Problem Solver: Eliminates slurry recirculation and solids grinding—common failures in conventional pumps. An adjustable wear ring maintains optimal suction-side clearance during operation, preventing performance degradation and particle damage.

• Efficiency Preservation: Maintains consistent flow and head without speed adjustments, cutting power consumption by up to 30% and extending component life.

Engineered for Longevity & Cost Savings

• Uniform Wear Patterns: Hydraulic optimization and high-grade wear materials (e.g., high chrome white iron) ensure predictable wear, reducing unplanned downtime.

• Robust Bearings: Reverse-taper roller bearings resist over-greasing and slurry ingress, while heavy-duty power frames withstand extreme loads for prolonged service life.

Industry-Leading Adaptability

• Retrofit-Ready Design: Wet ends integrate with competitor power frames for seamless performance upgrades, ideal for comparative testing or retrofits.

• Particle Protection: Critical for diamond and potash industries, preventing solids grinding to preserve product value.

Unmatched Features

• Adjustable Wear Ring Assembly: Enables real-time clearance adjustments during operation to eliminate recirculation.

• Optimized Hydraulics: Concentric casing (millMAX HH) and expelling vanes minimize radial thrust, ensuring stable performance across varying duty ranges.

• High-Pressure Capability: millMAX HP models handle >500 psi (35 bar) with tie-bolt casings for ultrasonic thickness monitoring and proactive maintenance.

• Low Maintenance Design: External adjustment bolts, wide suction-side clearances, and dry-gland seals simplify upkeep and reduce labor costs.
