Why choose the Danfoss SKP1NN Group 1 pump?

  • Larger shaft diameter than the SNP1 series — superior torque transmission, ideal for applications with high radial and axial shaft loads
  • SAE splined shaft (FA) — high-torque mechanical connection for direct PTO and compact gearbox drives
  • Anti-clockwise rotation (L) — specific configuration for installations requiring reverse rotation from standard
  • Pressure-balanced design — high volumetric efficiency and minimal wear across the full operating range
  • Extruded aluminium body — lightweight and structurally robust for harsh environments
  • Case-hardened steel gears — protection against wear, abrasion and fluid contamination
  • SKP1 displacement range: 1.2 / 1.7 / 2.2 / 2.6 / 3.2 / 3.8 / 4.3 / 6.0 / 7.8 / 10 / 12 cc/rev

Model code breakdown SKP1NN/4,3LN02FAP1C2C2NNNN/NNNNN:

  • SKP1NN → Group 1 gear pump — reinforced larger diameter shaft
  • 4,3 → 4.3 cc/rev displacement
  • L → Anti-clockwise rotation (viewed from shaft)
  • N → No integral pressure relief valve
  • 02 → SAE A flange — 2-bolt
  • FA → SAE splined shaft — high torque
  • P1 → Single shaft seal
  • C2/C2 → Metric female ports — inlet/outlet
  • NNNN/NNNNN → Standard configuration
