Notes:
1.The rotation speed shall not be less than 1450r/min for the pumps with the nominal displacement of 6 ml/r or 8 ml/r working under the pressure exceeding 16Mpa. 2. The highest rotation speed shall be limited within 1200r/min, while applying with water-based synthetic hydraulic fluids.
3. It is recommended to work with rotation speed of 1000r/min and maximum pressure of 12-14Mpa on the occasion where lower noise is strictly required. 4. Those pumps with the marks*belong to the extension specification of PV2R2-W group. Those pumps with the marks # belong to the extension specification of
PV2R3-W group. These two groups pump casing are 10mm longer than usual specification for special order.
5. The approximate calculation formula for driving power is as follows: the displacement of pump(mL/r) X the rotation speed of motor(r/min) X the working pressure
(Mpa)/49000. The unit for the final calculation result is KW.
