AT227318 Hydraulic Pump
| Déplacement | 12.5 CM³ / Rev (calibrated to John Deere OEM standards) | Fixed volume of hydraulic oil delivered per shaft rotation—defines flow rate at a given speed (no adjustability, ideal for constant-load tasks). |
| Notes de pression | – Continuous Operating Pressure: 16 MPA (160 bar)
– Intermittent Pressure: 20 MPA (200 bar) – Pression de pointe (≤3 seconds): 24 MPA (240 bar) |
Medium-pressure tolerance for typical agricultural tasks (par ex., lifting plows, operating loaders) without excessive wear. |
| Vitesse | – Vitesse nominale: 1,800 RPM (matches John Deere tractor PTO speeds)
– Vitesse maximale: 2,500 RPM – Vitesse minimale: 500 RPM |
Compatible with tractor power take-off (PDF) or engine-driven systems; minimum speed prevents cavitation (air bubble formation). |
| Débit | – At 1,800 RPM: 22.5 L/min (12.5 cm³/tr × 1,800 tr/min ÷ 1,000)
– At 2,500 RPM: 31.25 L/min |
Linear flow output—critical for consistent actuator speed (par ex., smooth loader lifting/lowering). |
| Efficacité | – Volumetric Efficiency: ≥88% (at rated pressure/speed)
– Mechanical Efficiency: ≥82% – Total Efficiency: ≥72% |
Balances energy use and performance; sufficient for non-high-precision agricultural applications. |
| Poids | ~7.5 kg | Lightweight for easy installation/retrofit in tractor engine bays or implement mounts. |
