Von Ruden MLHM-20-C-4B Hydraulic Motor Gerotor / Orbital

Description:

The Von Ruden MLHM-20-C-4B Hydraulic Motor is used in hydraulic power transmission systems to convert hydraulic fluid energy into rotary mechanical motion for industrial and mobile equipment. Commonly installed in conveyors, agricultural machinery, material handling equipment, winches, augers, and mobile hydraulic systems requiring high torque at low to moderate operating speeds. Maintenance teams and system integrators use this motor for replacement, retrofit projects, and hydraulic system repairs to maintain reliable torque output and equipment performance. The MLHM-20 designation corresponds to a compact gerotor-style hydraulic motor with approximately 20 cc/rev displacement.

Applications:

The Von Ruden MLHM-20-C-4B Hydraulic Motor is commonly used in conveyor drives, agricultural attachments, material handling systems, packaging machinery, mobile equipment, industrial automation systems, and hydraulic power units where compact size, smooth low-speed operation, and dependable torque generation are required. Hydraulic motors of this type are designed for continuous-duty industrial service and provide efficient rotary motion from hydraulic fluid power.
