3. Parameter Notes
- Flow Formula: Q(L/min) = Displacement(cc/rev) × Speed(rpm) ÷ 1000. Table calculated at 1450 rpm (common 4-pole motor).
- Estimated Power Formula: P(kW) = 17.5MPa × Q(L/min) ÷ (60 × η), η≈0.9. This is shaft power at full rated pressure. Recommend adding 10%~15% safety margin for motor selection.
- Pressure: 17.5 MPa rated for continuous operation; 21 MPa is only for short peak pressure, NOT for continuous duty.
- Speed: PV2R1 minimum recommended speed 750 rpm for adequate suction. PV2R3/PV2R4 large displacement models should NOT run continuously above 1800 rpm to avoid overheating and excessive noise.
- Weight: Same pump body shared for all displacements within one series, hence identical weight. PV2R4 has heavy weight; mounting base must have sufficient rigidity.
