Product Overview

As a classic radial piston drive unit, the Poclain MS11-MSE11 hydraulic motor is developed to satisfy the wheel drive demands of various off-highway mobile machines. Optimized cam curve and precision piston components minimize internal energy loss, guaranteeing consistent high torque output at low rotating speeds whether under intermittent or continuous operation.Thanks to its flexible modular design, users can select optional auxiliary modules such as static brakes and rotational speed detectors to realize personalized drive schemes. The robust body structure and wear-resistant sealing configuration strengthen adaptability to muddy, dusty and high-vibration construction sites. With unified installation standards, it allows convenient component replacement and routine maintenance, extensively utilized on road compaction machinery, municipal cleaning vehicles, farm machines and miniature mining equipment.

Key Features

• Ultra-large 1687cc displacement for extreme heavy loads Enormous displacement produces abundant startup, climbing and traction torque, meeting the strict power demand of super-heavy mobile engineering equipment.

• Radial piston direct drive structure Eliminates external reducer assemblies, shortens power transmission paths, reduces mechanical energy consumption and saves installation space.

• Superior high-pressure endurance Designed for high-pressure hydraulic circuits, it maintains stable torque output under sustained heavy-load operation in mining and quarrying environments.

• Versatile modular optional assemblies Can be equipped with built-in parking brake, speed monitoring sensor, flushing valve to fulfill various hydraulic control scheme requirements.

• Dual hydraulic circuit compatibility Works reliably for open-loop and closed-loop hydraulic systems, matching mainstream hydraulic system designs of heavy host machinery.

• High-hardness wear-resistant internal parts Precision machined alloy steel pistons and cam rings withstand long-term cyclic friction, significantly extending the whole motor service life.

• Reinforced cast iron outer housing Resists severe mechanical impact, continuous vibration, dust and moisture, perfectly suited for harsh underground, quarry and open construction working conditions.

• Fully interchangeable mounting dimensions Flange, drive shaft and oil port dimensions are consistent with original Poclain standards, no mechanical modification required during retrofit replacement.

• Optimized flow distribution design Reduces internal oil leakage and heat accumulation, elevates overall hydraulic system efficiency and lowers long-term operating expenditure.

• Wide ultra-heavy application coverage Applied for heavy road compactors, mining haulage trucks, large trenchers, quarry carriers and other heavy construction & mining machinery.
