PVB-10RSY-30-C-12 Hydraulic Piston Pump
| Theoretical Displacement | ~10 cm³/rev | Fixed displacement—flow output = displacement × shaft speed (e.g., 10 cm³/rev × 1500 rpm = 15 L/min, adjusted for volumetric efficiency). |
| Maximum Continuous Pressure | 30 MPa (4350 psi) | Safe long-term operating pressure; exceeding this causes premature wear of pistons and valve plates. |
| Peak Pressure | 35 MPa (5075 psi) | Short-duration pressure only (e.g., sudden load spikes); prolonged use leads to internal leakage. |
| Rated Speed | 1000 – 2500 rpm | Optimal speed range for high volumetric efficiency (≥90%) and low noise (≤75 dB(A) at 1m distance). |
| Minimum Speed | ≥500 rpm | Prevents cavitation (air bubble formation in oil); running below 500 rpm reduces suction efficiency and causes flow instability. |
| Hydraulic Fluid Compatibility | ISO VG 32/46/68 mineral-based hydraulic oil | Must meet cleanliness standard NAS 9 or higher (use 10–20 μm filtration to avoid contamination-related failures). |
| Operating Temperature Range | -15°C to +75°C (5°F to +167°F) | Extreme temperatures (below -15°C or above 75°C) thicken/thin oil, reducing pump efficiency and damaging seals. |
