SNP2 & SNP3 Series Hydraulic Gear Pump | SNP2NN 4.5 to 28cc | Charge Pump for HST Systems

SNP2 & SNP3 Series High-Performance Hydraulic Gear Charge Pumps

Product Overview: The SNP2 and SNP3 Series are the industry benchmarks for high-pressure aluminum gear pumps, specifically engineered as Charge Pumps for hydrostatic drive (HST) closed-loop systems and high-pressure actuators. This featured range covers the entire spectrum of displacements, from micro 4.5cc up to high-flow 28cc/rev, including core specifications: 011, 014, 017, 019, 022, 025, and 028. Built with high-strength extruded aluminum bodies and reinforced bearing blocks, these pumps ensure exceptional pressure stability and long-term durability in extreme operating environments.

Key Technical Advantages:

• 100% Plug-and-Play Replacement: Strictly manufactured to match international standard OEM parameters. Configuration codes like LRN01BAP1 guarantee that mounting flanges, drive shafts, and port configurations are 100% identical to original Danfoss units.

• Optimized for Charge Systems: Featuring superior suction capability and high-speed tolerance, providing stable oil circulation and charge pressure to the closed-loop circuit, effectively preventing main pump cavitation.

• Efficient Pressure Compensation: Equipped with automated axial gap compensation via floating bushes, maintaining a volumetric efficiency over 93% throughout its service life, reducing energy loss.

• Precision Displacement Range: Available in 4.5, 6.3, 8.2, 11, 14, 17, 19, 22, 25, and 28cc, satisfying diverse requirements from mini loaders to large-scale combine harvesters.

• Target Applications: Propulsion systems for road rollers, combine harvesters, concrete mixers, telehandlers, and medium-to-high pressure industrial Hydraulic Power Units (HPU).
