Poclain MS11 Motor | MS11-2-G21, MS11-2-G5E | Double Speed Radial Piston Motor

Poclain MS11 Series Double Speed Dual-Displacement Hydraulic Motors

Product Overview: The Poclain MS11 Series is a premier benchmark in global hydraulic propulsion technology. As a high-performance Low Speed High Torque (LSHT) radial piston motor, the MS11 is engineered to balance power and speed across diverse terrains. This page highlights precision Double Speed (Dual Displacement) models: MS11-2-G21 and the high-spec MS11-2-G5E-M11-1920-58EFJM. Featuring an integrated displacement shifting valve, this motor transitions seamlessly between “High Torque Mode” and “High Speed Travel Mode,” making it the ideal choice for skid steer loaders, rotary drilling rig power heads, harvesters, and specialized municipal vehicles.

Key Technical Advantages:

• Dual-Displacement Technology (1C/2C): Enables real-time displacement adjustment on-site, providing a perfect synergy between high tractive effort for heavy loading and high-speed mobility for transit.

• Series 2 Optimized Design: The MS11-2 features an enhanced fluid distribution system and upgraded sealing architecture, significantly improving volumetric efficiency and durability under extreme pressure.

• Peak Pressure & Load Resilience: Rated for 400 Bar continuous operation with peak capabilities reaching 450 Bar. Internal heavy-duty bearings support vehicle weight directly without external housings.

• Elite Low-Speed Smoothness: The patented cam-ring design ensures ultra-smooth operation even at speeds approaching 1 RPM, effectively eliminating “stick-slip” effects.

• Integrated Modular Features: Available with integrated multi-disc wet brakes, speed sensor ports, and specialized valve blocks to simplify hydraulic circuit plumbing.

• Target Applications: Mini-excavator travel, drilling rig rotation, road milling machines, and material handling cranes.
