Parker F11 Series Hydraulic Motor | F11-010-HF-IV-K | F11-019-MB-CV-K

The Parker F11 Series from LIC Hydraulic is a premium line of Bent-Axis Fixed Displacement Motors. Engineered for the most demanding applications, the F11 series utilizes a synchronized shaft and spherical piston design that provides unmatched volumetric efficiency and mechanical durability. Whether you are running at extreme speeds or under high-pressure spikes, models like the F11-010-HF-IV-K and F11-019-MB-CV-K deliver consistent, reliable power. We provide 100% drop-in replacements, matching original Parker mounting flanges (ISO, SAE, or CETOP) and spline/key shaft specifications.

Technical Highlights

• Series: F11-005, F11-006, F11-010, F11-012, F11-014, F11-019.

• Max Speed: Up to $10,000\text{–}14,000\text{ rpm}$ (depending on size).

• Operating Pressure: Continuous up to $350\text{ bar}$ ($5000\text{ psi}$); Intermittent up to $420\text{ bar}$.

• Design: 40-degree bent-axis technology with spherical pistons.

Core Advantages

• Unrivaled Speed Capability: The bent-axis geometry allows for high rotational velocities with minimal vibration, making the F11 series the global standard for high-speed saw and cutter drives.

• Superior Thermal Shock Resistance: The robust internal design allows the motor to handle rapid temperature changes and high-viscosity cold starts without seizing.

• High Power-to-Weight Ratio: Despite its compact footprint, the F11-019 can deliver immense power, reducing the overall weight and space requirements of your hydraulic system.

• Multi-Fluid Compatibility: Equipped with high-grade Viton (IV) or specialized seals, these motors are compatible with standard mineral oils and many fire-resistant hydraulic fluids.

Expert Maintenance Tips

• Case Drain Management: Like all high-performance piston motors, the F11 must have its case drain line connected to the reservoir through the highest available port. Excess case pressure will cause shaft seal failure and internal damage.

• Initial Startup: Ensure the motor case is filled with filtered oil before the first run. Spinning the motor at $10,000\text{ rpm}$ without internal lubrication will lead to instantaneous failure.

• Filtration Standard: To protect the precision-lapped valve plate and spherical piston rings, maintain system cleanliness at ISO 18/16/13. Particle contamination is the leading cause of internal friction and efficiency loss.
