Key Technical Advantages

• Geroler® Technology: The inclusion of rollers in the rotor set reduces friction during startup and rotation, providing higher mechanical efficiency and smoother operation at ultra-low speeds compared to standard gerotor sets.

• Precision Disc Valve Design: The independent valve disc rotates synchronously with the drive link, automatically compensating for wear to maintain constant efficiency throughout the motor’s service life.

• High-Pressure Shaft Seals: Engineered with premium materials, the shaft seal handles high back-pressure without leakage, allowing for simplified hydraulic circuit designs with fewer drain lines.

• Heavy-Duty Bearings: Large tapered roller bearings allow the motor to withstand substantial radial and axial loads, making it ideal for direct-drive winch and vehicle wheel applications.

Application Areas

• Material Handling: Conveyor drives, forklift attachments, and specialized lift systems.

• Agriculture: Reel drives for harvesters, seeders, and feeder mixers.

• Construction: Compact loader drives, augers, trenchers, and crane winches.

• Industrial: Power units for sweepers, waste compactors, and plastic processing machinery.

Expert Maintenance Tips

• Air Bleeding: Upon initial installation, jog the motor under no load to purge air from the housing. This prevents cavitation damage to the precise disc valve interface.

• Fluid Cleanliness: To maximize the lifespan of the Geroler set, maintain hydraulic fluid at ISO 4406 18/16/13 or cleaner.

• Drain Line Management: For systems with back-pressure exceeding $50\text{ bar}$ ($750\text{ psi}$) or frequent reversals, connecting the external case drain is highly recommended to protect the shaft seal and dissipate heat.
