I. Product Overview
• Model: A10VSO45DFR1/32R-VPB12N00 (or other suffix variants, such as -VPD72U99, depending on the supplier and configuration)
• Type: Swashplate-type axial piston variable displacement pump, designed specifically for open-circuit hydraulic drives.
• Key Features:
• Adjustable Flow Rate: Flow is proportional to drive speed and displacement, with stepless variable displacement achieved by adjusting the swashplate angle to meet varying flow demands under different operating conditions.
• High Pressure: Rated operating pressure up to 28 MPa (some sources indicate a continuous operating pressure of up to 280 bar; specific model and configuration should be confirmed).
• Low Noise & Long Service Life: Incorporates advanced design principles and manufacturing processes to ensure quiet operation and extended durability.
• Excellent Suction Performance: Ensures rapid oil suction during startup, minimizing cavitation and enhancing system stability.
• Robust Drive Shaft: Capable of withstanding both axial and radial loads, adapting to complex and variable operating conditions.
• Through-Shaft Design: Suitable for multi-circuit systems, improving system flexibility and reliability.
II. Technical Specifications (Example)
