Note: 1. When pressure of pumps exceeds 16MPa, with displacement of "4" "6" "8", speeds should be more than 1450r/min. 2. Reduce the negative pressure of the inlet when the single pumps or double pumps with large displacement at high speed. 3. In use of synthetic hydraulic fluids and water containing hydraulic fluids, limit the max speed at 1200r/min. 4. Speed at 1000r/min is suggested on occasions with lower noise strictly required. 5. Noisiness is available in working conditions of 14MPa and 1200r/min. 6. Input power is available in working conditions of 16MPa and 1500r/min. |

Frequently Asked Questions (FAQ)
What are the recommended operating speeds for the PV2R series vane pumps?
The standard speed range varies by model. For PV2R1, the speed range is 750 to 1800 r/min. For PV2R2 and PV2R3, the range is 600 to 1800 r/min. In applications where noise reduction is strictly required, a speed of 1000 r/min is suggested.
How does the choice of hydraulic oil affect the maximum pressure?
The maximum pressure depends on the type of oil used. For PV2R1, the maximum pressure is 21 MPa with special oil, 17.5 MPa with antiwear oil, and 16 MPa with common oil. Always consult the technical specifications table for specific model limits.
Are there speed limitations when using synthetic or water-containing hydraulic fluids?
Yes. When operating the PV2R series vane pumps with synthetic hydraulic fluids or water-containing hydraulic fluids, the maximum speed must be limited to 1200 r/min.
What should be considered when operating large displacement pumps at high speeds?
For single or double pumps featuring large displacements operating at high speeds, it is necessary to reduce the negative pressure at the inlet to ensure stable performance and prevent cavitation.
What installation shaft types are supported by the PV2R series?
The PV2R series supports standard shaft configurations, primarily Type F and Type F1, each with distinct dimensions for diameter, key width, and extension length as detailed in the installation dimensions tables.
Under what conditions are the stated input power and noise levels measured?
The input power ratings are based on working conditions of 16 MPa and 1500 r/min. The noise specifications are measured under working conditions of 14 MPa and 1200 r/min.
