V38D12RAX-95 Hydraulic Oil Piston Pump
| Theoretical Displacement | ~38 cm³/rev | Determines maximum flow output (flow = displacement × speed × volumetric efficiency). |
| Presión continua máxima | 28 MPA (4060 psi) | Presión de operación segura a largo plazo; exceeding this causes premature wear of pistons, valve plates, or seals. |
| Presión máxima | 35 MPA (5075 psi) | Short-duration pressure (≤5 segundos) for emergency heavy loads (P.EJ., sudden machine jolts); avoid prolonged use. |
| Velocidad nominal | 1000 – 2500 rpm | Rango de velocidad óptimo para alta eficiencia volumétrica (≥91%) y bajo ruido (≤76 dB(A) at 1m distance). |
| Velocidad mínima | ≥600 rpm | Previene la cavitación (air bubble formation in oil); running below 600 rpm reduces suction efficiency and causes flow instability. |
| Compatibilidad de fluido hidráulico | ISOS VG 32/46/68 mineral-based hydraulic oil | Must meet cleanliness standard NAS 8 o más alto (usar 10 μm filtration to avoid contamination of precision internal components). |
| Rango de temperatura de funcionamiento | -15° C a +80 ° C (5° F a +176 ° F) | Extreme temperatures (below -15°C or above 80°C) thicken/thin oil, reducing pump efficiency and damaging seals. |
