Features

    • 11" Stroke Advantage: Delivers up to 37% more displacement per revolution versus conventional 8” pumps, reducing fatigue cycles and wear while fully utilizing the RPM range for higher output.
    • Smart Gearing System: Rated at 3,600 HP with a 7.5:1 gear ratio, it’s built to operate within the complete RPM range of natural gas and dual-fuel power sources, maximizing output while minimizing mechanical stress.
    • Component Protection: Greater flow per stroke reduces cycle rate, extending wear life of power end and fluid end parts including valves, seats, packing, crossheads, and bearings.
    • Maintenance Reduction: Field-validated results show operators reporting up to 25 fewer valve and seat replacements per month across a 20-pump fleet, resulting in 125 fewer valves and seats a month.
    • High-Integrity Frame: Thick-section skin plates, reinforced frame rings, and proprietary weld processes provide structural rigidity and resistance to high-load flex and fatigue.
    • Long-Life Tie Rods: Designed to last the full lifecycle of the power end without replacement.
    • Proprietary Bearings: Custom main bearing design ensures longer life and higher performance under continuous load.
    • Robust Crankshaft: Engineered to resist deflection under high operating loads, enhancing durability and longevity.
    • Modular Assembly: Includes removable gearbox and stuffing box, plus a reversible crosshead and housing for extended operational life and easier service.
    • Compact & Lightweight: Up to 4,000 lbs. lighter than comparable 5,000 HP pumps, reducing rig-up time, axle loading, and footprint.
    • Field-Proven Stuffing Box: Bolt-on design simplifies maintenance and improves sealing performance.
    • Patented Valve Cover Seal: Moveable technology doubles valve cover seal bore life, reducing wear, extending uptime, and lowering maintenance frequency.
    • Optimized Thread Design: Advanced crossbore and thread geometry improves fatigue life and increases retainer nut durability by 3X.
    • Eliminated Brass Crosshead Guide Sleeve: Improves serviceability by reducing repair labor, shortening maintenance cycle times, and lowering parts inventory requirements.
    • Fewer Bolts on Fluid Ends: Provides quicker access for maintenance, reduces service time, and lowers spare parts requirements
    • Greater Clearance in Cradle Area: Improves accessibility during plunger and packing service procedures
