Product Description
NSh Series High-Performance Hydraulic Gear Pumps for MTZ & Crawler Tractors
Product Overview: The NSh (НШ) Series is the definitive power core for Eastern European agricultural machinery and heavy-duty crawler tractor hydraulic systems. Renowned for their robust cast construction and exceptional durability, these pumps are engineered specifically for continuous operation in harsh agricultural environments and under high-intensity loads. This range features the complete spectrum of core models: from the compact NSh16, NSh20, and NSh25 to the mainstream NSh32M-3, NSh40, and the heavy-duty NSh50M-3 and NSh100. Utilizing advanced pressure-balanced compensation technology, the NSh series maintains a volumetric efficiency above 92%, serving as the premier power source for MTZ tractor lifters and steering systems.
Key Technical Advantages:
Superior Durability & Reliability: Crafted with high-strength wear-resistant alloy bodies, offering an excellent power-to-weight ratio to ensure long service life in high-dust and high-vibration extreme environments.
High-Pressure Capability: Rated for working pressures up to 16-20 MPa (160-200 Bar), with stable peak performance ensuring reliable power output for heavy-duty crawler machinery.
Peak Volumetric Efficiency: Equipped with automated axial gap compensation that adjusts in real-time to system pressure, minimizing internal leakage and maximizing performance.
Standard Compatibility: Strictly adheres to MTZ and Eastern European agricultural standards, providing standard 4-bolt/6-bolt splined shafts and rectangular flanges for seamless connection to host machines.
Target Applications: MTZ wheel tractors, DT-75 / T-130 / T-170 crawler tractors, harvester lifting circuits, and agricultural hydraulic power units.
