OMFB HDS 64 ISO Bent Axis Piston Pump | 601-001-10649 | 601-001-10643

LIC Hydraulic offers the OMFB HDS 64 ISO Series, high-performance bent-axis axial piston pumps specifically engineered for heavy-duty truck PTO (Power Take-Off) applications. With a displacement of $64\text{ cc/rev}$ and a continuous pressure rating of $350\text{ bar}$ ($5000\text{ PSI}$), the HDS series excels in providing reliable hydraulic power for cranes, tippers, and specialized vocational trucks. Models 601-001-10649 (CCW) and 601-001-10643 (CW) feature a standard ISO 4-bolt flange, ensuring a seamless fit for European and international truck chassis.

Technical Specifications (Quick Reference)

• Displacement: $64.12\text{ cc/rev}$.

• Max Operating Pressure: Continuous $350\text{ bar}$, Intermittent $400\text{ bar}$.

• Speed Range: Continuous speed up to $1900\text{ RPM}$, max intermittent $2500\text{ RPM}$.

• Mounting: ISO 7653 4-bolt flange with $8\text{x}32\text{x}36$ DIN spline shaft.

• Rotational Direction: Available in Left-Hand (CCW) and Right-Hand (CW).

Key Technical Advantages

• Bent-Axis Reliability: The bent-axis geometry allows for higher mechanical efficiency and is less sensitive to fluid contamination compared to swashplate designs.

• Compact High-Power Output: Designed for the tight mounting spaces on truck gearboxes while delivering power densities required for heavy lifting.

• Reinforced Bearing System: Tapered roller bearings handle high radial and axial loads, extending the service life under high-speed operation.

• Robust Sealing: Equipped with high-pressure shaft seals that resist leakage even under frequent pressure spikes common in mobile hydraulics.

Application Areas

• Knuckle Boom Cranes: Providing the high-pressure flow needed for telescopic booms and stabilizers.

• Heavy Duty Tipping Gear: Rapid cylinder extension for large-scale mining and construction dump trucks.

• Skip Loaders & Hooklifts: Fast and reliable power for heavy material handling.

• Aerial Platforms: Smooth hydraulic actuation for safe operator positioning.

Expert Maintenance Tips

• Direction of Rotation: Always verify your PTO rotation before ordering. Using the 601-001-10643 (CW) on a CCW PTO will cause instant damage due to lack of lubrication in the suction port.

• Priming: Before initial startup, the pump housing must be primed with clean hydraulic oil. “Dry starts” will lead to immediate catastrophic failure of the piston shoes.

• Filtration Integrity: Maintain oil cleanliness to ISO 4406 18/16/13. Particle contamination is the primary cause of internal scoring in high-pressure bent-axis pumps.
