MSI & MA Series Heavy-Duty High-Pressure Axial Piston Motors and Pumps

Product Overview: The MSI and MA series are axial piston hydraulic motors and pumps engineered for the most demanding environmental conditions. This series covers a comprehensive displacement range from the compact 50cc (MA50/MSI50) to the high-power 180cc (MA180). Featured models like MSI108, MSI125, and MA125 are renowned for their superior power density and high starting torque. Their rugged architecture ensures stable operation under continuous high pressure, making them the premier choice for crawler travel drives, heavy-duty winches, construction machinery power heads, and mining equipment hydraulic drive systems.

Key Technical Advantages:

• Extreme Torque Output: Optimized rotating group design ensures massive output torque even at low speeds, ideal for heavy-load startup conditions.

• High Pressure & Shock Resistance: Rated for continuous operation at 350-400 Bar, with reinforced housings and high-strength pistons designed to withstand frequent load fluctuations.

• Superior Volumetric Efficiency: Precision-engineered valve plates minimize internal leakage, maximizing energy conversion efficiency and reducing system heat.

• Versatile Mounting Configurations: Available with diverse ISO and SAE standard flanges and shaft options, including specific configurations like MSI108R, ensuring seamless “drop-in” replacement.

• Heavy-Duty Bearing Architecture: Equipped with oversized bearings for exceptional radial and axial load capacity, extending service intervals in harsh environments.
