Rexroth Hydraulic Pump PV7-1A/25-45RE01MC0-08 Grey Easy Maintenance Long Service

Product Specification

Description:

The Rexroth hydraulic pump PV7-1A/25-45RE01MC0-08 is a variable displacement vane pump manufactured by Bosch Rexroth Corporation in Germany. It primarily consists of a pump body, end cover, rotor, vanes, stator ring, compression spring, adjustment screw, and distribution plate. The pump adopts a swashplate structure, achieving displacement regulation by adjusting the eccentricity between the stator and rotor. Its operating principle involves utilizing the rotation of the rotor and the sliding of the vanes to form sealed working chambers, thereby enabling the suction and discharge of hydraulic fluid.
 

Application Areas:

Industrial Hydraulic Systems: Suitable for applications requiring continuous operation with significant fluctuations in flow demand, such as hydraulic drive systems for machine tools, injection molding machines, and other equipment. In these devices, the pump can automatically adjust the flow rate according to different working stages to meet the needs of the equipment under various operating conditions, thereby improving production efficiency and the stability of equipment operation.
Construction machinery: It can be used in the hydraulic systems of construction machinery such as excavators and loaders to provide power support for equipment operations. For example, during excavation and rotation operations of an excavator, the pump can quickly respond to operator control commands to achieve precise flow control, thereby improving operational efficiency and operational accuracy.
Ship hydraulic systems: It is also applied in hydraulic equipment such as ship steering gear and cargo cranes. It ensures the stable and reliable operation of ship hydraulic equipment under prolonged operation and complex conditions, providing safety assurance for ship navigation and operations.
Metallurgy industry: It can be used in the hydraulic control systems of metallurgical equipment such as rolling mills and continuous casting machines. In these equipment, the pump can withstand high working pressures and large flow demands, ensuring the normal operation of the equipment and the continuity of the production process.
Plastic machinery: In plastic molding equipment such as injection molding machines and extruders, the pump can be used to control mold opening/closing and material conveyance. Its variable displacement feature automatically adjusts flow according to different production stages, improving equipment production efficiency and product quality.
 

Advantages:

Energy-efficient: The pump features variable displacement functionality, automatically adjusting flow rates according to system requirements to avoid energy waste in partial-load conditions. In practical applications, compared to fixed-displacement vane pumps, it has lower power loss and heat generation, significantly reducing equipment energy consumption and operational costs.
Smooth operation: Due to the flexible sliding of the vanes within the rotor slots and the eccentricity between the rotor and stator, the pump operates smoothly with uniform flow output. This helps reduce pressure fluctuations and shocks in the hydraulic system, enhancing system stability and reliability while extending equipment lifespan.
Low noise: Special design and optimization measures, such as adjusting height-adjustable screws, effectively reduce operational noise. In industrial production environments, low-noise hydraulic pumps provide operators with a more comfortable working environment and reduce noise pollution.
Long service life: The internal sliding bearings use fluid dynamic lubrication, effectively reducing bearing wear and extending bearing service life. Additionally, the pump's compact structure and high manufacturing precision of components further enhance its overall reliability and durability.
High control accuracy: It has low hysteresis characteristics, enabling rapid and precise pressure and flow control. In hydraulic systems requiring high-precision control, such as CNC machine tools and automated production lines, this pump can meet strict control requirements, improving equipment processing accuracy and production efficiency.
Strong adaptability: This pump has a wide operating pressure range, up to 160 bar, capable of adapting to different pressure requirements. Additionally, its installation and connection dimensions comply with VDMA 24560/1 and ISO 3019-2 standards, facilitating integration with other hydraulic components and ensuring good compatibility and interchangeability.
Easy maintenance: Its rational structural design facilitates disassembly and maintenance. During repairs or component replacements, operations are simple and efficient, reducing downtime and maintenance costs.
