OMFB HDS HDT Series Piston Pump | HDT ISO 108 D(R) | 602-001-1108 | Truck Hydraulic Pump

The OMFB HDS and HDT Series from LIC Hydraulic are high-performance Axial Piston Pumps engineered specifically for the global truck and mobile equipment market. Designed for direct mounting on power take-offs (PTOs), models like the HDT ISO 108 DR (Part No. 602-001-1108) deliver massive hydraulic power within a compact, standardized frame. Fully compliant with the ISO 7653 interface, these pumps are the industry standard for high-pressure tipper and crane applications. We provide 100% drop-in replacements, ensuring total compatibility with original OMFB shaft, flange, and clockwise (Right-hand) rotation requirements.

Technical Highlights

• Series: HDS (High Strength), HDT (Heavy Duty Truck).

• Displacement: $47, 96, 108\text{ cc/rev}$.

• Max Pressure: Continuous $350\text{ bar}$ ($5075\text{ psi}$), Peak up to $400\text{ bar}$.

• Standards: ISO 7653 4-bolt flange, $8\times 32\times 36$ spline shaft.

• Rotation: Right-hand (Clockwise) as specified.

Core Advantages

• Superior Power Density: The HDT 108 series utilizes a bent-axis piston design that provides higher torque and pressure than conventional gear pumps, allowing for faster cycle times and heavier lifting capacities.

• Direct PTO Integration: The ISO 4-bolt mounting eliminates the need for intermediate cardan shafts or mounting brackets, reducing mechanical losses and installation time on modern chassis.

• Thermal & Volumetric Efficiency: Precision-ground pistons and high-load bearings ensure that the pump maintains peak efficiency even during long duty cycles or under high ambient temperatures common in construction sites.

• Rugged Reliability: Engineered to withstand the extreme vibration and pressure spikes inherent in mobile hydraulics, featuring a robust cast-iron housing and premium internal seals.

Expert Maintenance Tips

• Rotation Verification: Before installing the 602-001-1108, ensure your PTO rotates in the correct counter-clockwise direction (to drive the Right-hand pump). Running the pump in the wrong direction will destroy the internal valve plate and shaft seal instantly.

• Initial Lubrication: Always fill the pump housing with clean hydraulic oil before engaging the PTO for the first time. Operating a dry piston pump will lead to catastrophic metal-on-metal failure within seconds.

• Suction Hose Diameter: For a large displacement pump like the HDT 108, use a heavy-duty, non-collapsible suction hose of at least $2\text{–}2.5$ inches to prevent cavitation at high engine speeds.
