Poclain MK Series Ultra-Compact Radial Piston Hydraulic Motors

Product Overview: The Poclain MK Series is synonymous with high-performance, compact drive solutions for global industrial and mobile machinery. As a Low Speed High Torque (LSHT) radial piston motor, the MK series is specifically engineered for applications where axial installation space is at a premium. This featured selection covers the entire spectrum from light-duty to heavy-duty frames: MK04, MK05, MK08, MK09, MK35, and MK47. It includes precision configurations like MK04-2-114-K04-3340-3000 and MK05-2-124-F04-1340-0000. Renowned for its superior efficiency and rugged build, the MK series is the premier choice for rotary drilling rig heads, skid steer drives, industrial mixers, forestry machinery, and specialized compact chassis.

Key Technical Advantages:

• Ultra-Short Axial Profile: By optimizing fluid distribution, the MK series offers a significantly shorter axial length than the MS series of the same displacement, perfect for drilling head integration.

• Elite Low-Speed Smoothness: Patented cam-ring technology ensures the motor delivers full rated torque at zero RPM or during startup, effectively eliminating “stick-slip” effects.

• Highly Modular Functionality: Options for integrated multi-disc wet parking brakes (e.g., F04 series), dual-displacement shifting valves, and various speed sensor ports.

• Superior Shock Resilience: Extreme structural rigidity allows the motor to handle frequent directional reversals and massive radial loads from harsh terrains with ease.

• High-Pressure Reliability: Rated for continuous operation at 400 Bar with peak capabilities reaching 450 Bar, ensuring extended service life under heavy duty cycles.

• Target Applications: Drilling rig rotary drives, crawler propulsion, marine winch systems, municipal maintenance vehicles, and road milling machines.
