Poclain MKD04 Motor | MKD04-2-114-K04 | High Torque Double-Row Piston Motor

Poclain MKD04 Series Compact High-Displacement Radial Piston Motors

Product Overview: The Poclain MKD04 Series is the advanced solution for compact hydrostatic travel drives. As an enhanced version of the MK series, the MKD04 utilizes a precision Double-Row Piston design to significantly boost torque output and power density without increasing the motor’s outer diameter. This High Torque Low Speed (HTLS) motor is specifically engineered for environments with extreme space constraints but heavy load requirements. Featuring the configuration MKD04-2-114-K04-3340-37MZ, this series is the premier choice for skid steer loaders, small drill heads, municipal specialized sweepers, and industrial winch systems.

Key Technical Advantages:

• Ultimate Compactness & High Torque: The unique MKD architecture maintains a superior footprint while providing the immense traction needed to drive medium-sized machinery.

• Dual-Displacement (2-Speed) Capability: The MKD04-2 designation identifies its displacement switching functionality, allowing equipment to toggle seamlessly between “High-Torque Work Mode” and “High-Speed Travel Mode.”

• Robust Load Resilience: The K04 (Shaft interface) is reinforced to handle frequent direction reversals and high-impact shock loads, ensuring long-term drivetrain stability.

• Integrated Custom Sealing: The suffix 37MZ denotes specialized sealing logic and internal coatings, optimized for harsh environments involving high dust, moisture, or corrosive elements.

• Target Applications: Wheeled/Tracked mini-excavators, material handling hoists, automated warehouse robotics, and road milling auxiliary drives.
