Linde HMF Series Motor | HMF50, HMF75, HMF105 | 420 Bar High Pressure Hydraulic Motor

Linde HMF Series High-Pressure Fixed Displacement Hydraulic Motor

Product Overview: The Linde HMF series is a high-pressure fixed displacement axial piston motor engineered specifically for closed-circuit hydrostatic transmissions. Featuring a robust swashplate design, the HMF range (covering 50, 55, 75, and 105cc) is renowned for its exceptional power-to-weight ratio and superior starting torque. Designed to withstand the most grueling shock loads in mobile machinery, these motors deliver stable speed output under high pressure—the premier choice for precise control in travel drives and winch systems.

Key Technical Advantages:

• Superior Starting Torque: Optimized valve plate and piston group geometry ensure maximum torque availability from a standstill, significantly enhancing heavy-duty climbing and startup performance.

• Heavy-Duty High-Pressure Reliability: Rated for an operating pressure of 420 Bar (6100 PSI) with peak capabilities up to 500 Bar. The rigid swashplate support structure ensures extended service life under extreme duty cycles.

• Integrated Closed-Loop Solutions: Features optional integrated flushing and boost pressure relief valves to efficiently dissipate heat and purify oil within closed circuits, keeping system temperatures low.

• Compact Power Density: Utilizing advanced material science, the HMF series delivers massive power output within a minimal installation envelope, ideal for tight wheel-end drives or winch drum integrations.
