Deliver relentless, constant power to your most demanding hydrostatic transmissions with the THM MFS Series Fixed Displacement Axial Piston Motor. Built on the proven, heavy-duty foundation of the Sauer 20 Series, this advanced swashplate motor is engineered to perform flawlessly in incredibly tough industrial and mobile environments. Capable of withstanding massive maximum pressures up to 420 bar across a displacement range of 33 to 90 cm³/rev, the MFS Series guarantees reliable, highly efficient mechanical energy transfer. When your machinery requires unwavering torque and steady speed without the complexity of variable controls, this compact motor is the ultimate fluid power solution.

Core Technical Specifications:-

• Motor Architecture: Fixed Displacement Axial Piston Motor (Swashplate Design)
• Displacement Sizes: 33 to 90 cm³/rev
• Maximum Operating Pressure: 420 bar
• Mounting Compatibility: Fully SAE Standard Compliant

Key Features & Engineering Advantages:-

• Advanced Swashplate Mechanics: Features a compact, highly effective swashplate design that consistently delivers unwavering power, making it the ideal motor for systems that require steady, fixed-output torque and speed.
• Extreme Pressure Tolerance: Built with robust internal components designed to safely and reliably operate at maximum peak pressures up to an incredible 420 bar.
• High-Speed Stability: Equipped with specialized lightweight plungers that significantly reduce internal inertia. This guarantees excellent performance and prevents damaging vibrations at high rotational speeds.
• Heavy-Duty Load Handling: Integrates premium tapered roller bearings engineered to easily absorb and handle substantial radial and axial shaft loads from heavy external machinery.
• Harsh Environment Durability: Features a highly resilient bimetallic bearing plate alongside advanced face and lip seals. This ensures the internal system remains completely sealed from the outside, allowing it to thrive in dusty, hot, and humid conditions.
• Low-Maintenance Simplicity: Because it is a fixed displacement motor, it requires fewer moving parts than variable alternatives. This results in highly efficient energy transfer, exceptional durability, and drastically reduced maintenance requirements.

Working Principle:-

The THM MFS Series operates on a highly efficient hydrostatic swashplate principle. Hydraulic fluid enters the motor port and fills the cylinder block. As the fluid applies pressure, it forces the pistons—which are arranged parallel to the drive shaft—to push against the angled swashplate. This back-and-forth motion converts the hydraulic energy into steady mechanical rotation. Because the displacement is fixed, the motor delivers the exact same torque and speed with every single rotation (determined by the system's input flow and pressure).

Ideal Industry Applications:-

The unyielding torque and heavy-duty reliability of the MFS Series make it a universally adaptable hydraulic drive across multiple sectors:

• Mobile & Construction Equipment: Skid steers, compact loaders, agricultural tractors, combine harvesters, and forestry crushers.
• Heavy Industrial Machinery: High-capacity conveyor drive systems, injection molding machines, and heavy rotary drives.
• Hydrostatic Transmissions: Closed-loop drive systems, utility vehicles, road rollers, and heavy-duty forklifts.
• Marine & Offshore: Deck machinery, anchor handling equipment, and heavy-duty winch drives.
• Renewable Energy: Wind turbine pitching systems and heavy-duty hydraulic solar trackers.
