CBHZQA-F25-AL Hydraulic Gear Pumps
| Theoretical Displacement | ~25 cm³/rev | Fixed displacement—defines the maximum oil volume the pump can deliver per shaft rotation. |
| Presiunea continuă maximă | 16 MPA (2320 psi) | Presiune de funcționare sigură pe termen lung; exceeding this causes accelerated wear of gear teeth and seals. |
| Presiunea maximă | 20 MPA (2900 psi) | Short-duration pressure (≤3 seconds) for temporary load spikes (e.g., sudden startup of a hydraulic cylinder); avoid prolonged operation at peak pressure. |
| Rated Flow (la 1500 RPM) | ~37.5 L/min (litri pe minut) | Calculated as: Displacement × Speed ÷ 1000 (25 CM³/Rev × 1500 RPM ÷ 1000 = 37.5 L/min); actual flow is slightly lower due to volumetric efficiency. |
| Viteză nominală | 1000 – 2000 RPM | Interval de viteză optim pentru eficiență volumetrică ridicată (≥88%) and low operating noise (≤72 dB(O) at 1m distance). |
| Viteză minimă | ≥500 rpm | Previne cavitația (air bubble formation in oil) and ensures consistent oil suction; running below 500 rpm leads to flow instability. |
| Compatibilitatea lichidului hidraulic | ISOS VG 32/46/68 mineral-based hydraulic oil | Must meet cleanliness standard NAS 9 sau mai mare (use 10–20 μm filtration to avoid gear wear from contamination). |
| Interval de temperatură de funcționare | -10°C to +75°C (14°F to +167°F) | Extreme temperatures degrade oil viscosity and NBR seals; use oil heaters (for < -10°C) or coolers (for > 75°C) if needed. |
