Ordering code for standard program：
The 1PV2V3 series is engineered as a reliable core component in advanced hydraulic systems, widely applied in machine tools, construction machinery, and industrial equipment. These pumps offer precise flow regulation and robust performance under diverse operating conditions, making them ideal for applications requiring dynamic pressure control and energy efficiency.
Key Performance Features:
Working Pressure Range: 12–100 bar (with peak up to 120 bar)
Displacement Range: 10–100 cc/rev, with variable adjustment capability
Model Designation Example: Suffix “MC25A1” indicates a displacement of 25 cc/rev
Adjustment Precision: ±2% accuracy, response time ≤0.5 seconds—ideal for precision control environments
Efficiency Standards: Volumetric efficiency ≥92%, mechanical efficiency ≥85%, surpassing industry benchmarks for vane pump energy performance
Temperature Management: Designed for continuous operation with oil temperature maintained at ≤65°C (cooling system recommended)
Construction: Cast iron housing with single-stage design, compatible with standard hydraulic oil media
Flow Regulation Mechanism:
Flow is easily adjusted via an integrated handle system:
For light-load stabilization: Adjust the grey lock nut and rotate the yellow ring clockwise (~15° increments).
Under heavy-load stall conditions: Use the blue lock nut and red adjusting ring similarly to restore stable pressure output.
Installation & Operational Guidelines:
To ensure optimal performance and longevity:
Maintain proper tank ventilation or use pressurized tanks to prevent suction deficiency
Install a filter at the suction port and ensure pipeline bends have a radius of at least 1.5× the pipe diameter to avoid cavitation
Prior to initial startup, fill the pump with oil and perform a 5-minute no-load run to purge air
Maintenance Guidelines:
To ensure long service life and consistent performance, we recommend the following maintenance practices:
Regular inspection of seals and filter elements—deteriorated hydraulic oil can accelerate pump wear
Replacement of the filter element every 500 operating hours
Inspection of the variable mechanism for wear every 2,000 hours
Use of ISO VG46 anti-wear hydraulic oil with a viscosity range of 40–100 cSt for optimal lubrication and system protection
Troubleshooting Support:
Common operational issues can be efficiently addressed through targeted diagnostics:
Insufficient flow or abnormal pressure: Inspect the distribution mechanism and sealing components
Stuck variable mechanism: Clean the regulating valve or replace contaminated hydraulic oil
Pressure fluctuations: Likely caused by wear on the distribution plate—check for surface damage or consider replacement
Abnormal noise: Often due to oil contamination; a thorough cleaning of the fuel tank and filtration system is recommended
Key Precautions:
Conduct regular checks on seal integrity to prevent leakage and maintain system efficiency
Avoid extended operation under overpressure conditions to protect the contact surfaces between blades and stator from premature wear
Model Examples:
1PV2V3-40/12RA01MC100A1: 40 cc/rev displacement, 12 bar pressure, with variable control
1PV2V3-30/63RA01MC25A1: 30 cc/rev, 63 bar—suitable for integration into high-pressure hydraulic systems
Industry Applications:
These pumps are engineered to meet diverse industrial needs, including:
Construction Machinery: Compatible with the walking motor drive systems of excavators
Machine Tools: Ideal for rapid clamping applications using hydraulic chucks (capable of meeting ≥80 bar pressure requirements)
General Industrial Systems: Effective in hydraulic pressure control and lubrication circuits across variable load conditions
