Sauer Danfoss SNP1NN Series Gear Pump

SKU: Sauer Danfoss SNP1NN Series Gear Pump

The Sauer Danfoss SNP1NN (now Danfoss Power Solutions) is a high-performance external gear pump belonging to the Group 1 family. As the direct successor to the legacy SNP1 series, the SNP1NN offers enhanced durability and efficiency in a lightweight aluminum body. It is designed for small mobile and industrial hydraulic systems requiring reliable pressure up to 250 bar.

Key Features:

Series: SNP1NN (Group 1)
Displacement: 1.2 to 12.0 cm³/rev
Max. Pressure: Up to 250 bar (Continuous)
Design: Pressure-balanced, aluminum housing.

Product Overview The Sauer Danfoss SNP1NN Series represents the latest generation of Group 1 gear pumps. Engineered with a high-strength extruded aluminum body and pressure-balanced bushing blocks, the SNP1NN ensures consistent volumetric efficiency and minimal internal leakage. It is widely used in applications where space is limited but high power density is required. This series is fully interchangeable with the older Sauer Danfoss SNP1 models.

Why Choose Danfoss SNP1NN?
