V38D12RAX-95 Hydraulic Oil Piston Pump
| Theoretical Displacement | ~38 cm³/rev | Determines maximum flow output (flow = displacement × speed × volumetric efficiency). |
| Massima pressione continua | 28 MPA (4060 psi) | Pressione operativa sicura a lungo termine; exceeding this causes premature wear of pistons, valve plates, or seals. |
| Pressione di picco | 35 MPA (5075 psi) | Short-duration pressure (≤5 secondi) for emergency heavy loads (per esempio., sudden machine jolts); avoid prolonged use. |
| Velocità nominale | 1000 – 2500 RPM | Intervallo di velocità ottimale per alta efficienza volumetrica (≥91%) e basso rumore (≤76 dB(UN) at 1m distance). |
| Velocità minima | ≥600 rpm | Impedisce la cavitazione (air bubble formation in oil); running below 600 rpm reduces suction efficiency and causes flow instability. |
| Compatibilità del fluido idraulico | Isos vg 32/46/68 mineral-based hydraulic oil | Must meet cleanliness standard NAS 8 o superiore (utilizzo 10 μm filtration to avoid contamination of precision internal components). |
| Intervallo di temperatura operativo | -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. |
