111.12.029.0A - GEAR PUMP GR1 SKP1NN 4.3 CC/REV - DANFOSS
Danfoss SKP1NN Group 1 external gear pump, 4.3 cc/rev fixed displacement, anti-clockwise rotation, 250 bar rated pressure. SAE A 2-bolt flange, reinforced SAE splined shaft (FA), metric female ports. SKP1 version with larger shaft diameter than SNP1 — designed for high-torque applications and elevated radial shaft loads.
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
