11039730 - GEAR PUMP GR3 SNP3NN 22 CC/REV - DANFOSS

Danfoss SNP3NN Group 3 external gear pump, 22.1 cc/rev fixed displacement, clockwise rotation, 250 bar rated pressure. SAE B 4-bolt flange, SAE 9-tooth splined shaft, SAE O-ring boss ports. Theoretical flow up to 44 l/min at 2,000 rpm. Minimum displacement variant of the GR3 range for mobile and industrial applications requiring Group 3 structural robustness.

Price available only for registered users

Why choose the Danfoss SNP3NN Group 3 pump?

  • Pressure-balanced design — maximum volumetric efficiency and minimal wear across the full operating range
  • High-strength extruded aluminium body — robust and lightweight structure for harsh environments
  • Case-hardened steel gears — protection against wear, abrasion and fluid contamination
  • SAE B 4-bolt flange — ultra-robust mounting for high-vibration and high-torque applications
  • SAE 9-tooth splined shaft — reliable torque transmission for direct drives
  • SAE O-ring boss ports — superior sealing on high-pressure connections
  • Multi-pump configurations available — stackable with SNP1NN, SNP2NN and SNP3NN
