V38D12RAX-95 Hydraulic Oil Piston Pump
| Theoretical Displacement | ~38 cm³/rev | Determines maximum flow output (flow = displacement × speed × volumetric efficiency). |
| Pression continue maximale | 28 MPA (4060 psi) | Pression de fonctionnement à long terme sûre; exceeding this causes premature wear of pistons, valve plates, or seals. |
| Pression de pointe | 35 MPA (5075 psi) | Short-duration pressure (≤ 5 secondes) for emergency heavy loads (e.g., sudden machine jolts); avoid prolonged use. |
| Vitesse nominale | 1000 - 2500 RPM | Plage de vitesse optimale pour une efficacité volumétrique élevée (≥91%) et un faible bruit (≤76 dB(UN) at 1m distance). |
| Vitesse minimale | ≥600 rpm | Empêche la cavitation (air bubble formation in oil); running below 600 rpm reduces suction efficiency and causes flow instability. |
| Compatibilité du liquide hydraulique | ISOS VG 32/46/68 mineral-based hydraulic oil | Must meet cleanliness standard NAS 8 ou plus (use 10 μm filtration to avoid contamination of precision internal components). |
| Plage de température de fonctionnement | -15° C à + 80 ° C (5° F à + 176 ° F) | Extreme temperatures (below -15°C or above 80°C) thicken/thin oil, reducing pump efficiency and damaging seals. |
