Product Description
NSh Series High-Pressure Hydraulic Gear Pumps for Tractors & Asphalt Pavers
Product Overview: The NSh (НШ) Series Gear Pump serves as the primary power core for heavy-duty agricultural machinery and road construction equipment. This featured selection covers the full spectrum of precision models, from the compact NSh10R and mainstream NSh32R, NSh50R, to the high-capacity NSh100. Engineered to rigorous industrial standards, these pumps are specifically designed to meet the hydraulic demands of tractors (such as MTZ, DT series) and asphalt pavers operating under harsh conditions. Their robust cast aluminum or iron housing ensures exceptional stability at peak pressures up to 25 MPa.
Key Technical Advantages:
Superior Environmental Resilience: Built for dusty, high-temperature, and high-intensity environments, offering excellent wear resistance—ideal for pavers and agricultural tractors.
High Volumetric Efficiency: Utilizing classic axial gap compensation technology, these pumps maintain efficiencies over 92% throughout their service life, minimizing power loss.
Flexible Rotation Configurations: Available in R (Clockwise / CW) and Counter-clockwise (CCW) versions, ensuring a perfect match with various engine drive ends.
Simple & Low Maintenance: The simplified internal structure allows for high parts interchangeability, significantly reducing field repair difficulty and operational costs.
100% Plug-and-Play Replacement: Strictly adheres to original NSh standard dimensions, ensuring identical flange patterns, splined shaft ends, and port specifications for seamless installation.
