Product Specification

Description:

The Rexroth Hydraulic Pump A10VSO71DR/31R-PPA12N00 is a variable displacement axial piston pump featuring a swashplate design, specifically engineered for static hydraulic drives in open-loop systems. It belongs to the A10VSO series, renowned for its efficiency, reliability, and versatility. The A10VSO71DR/31R-PPA12N00 has a rated pressure of 280 bar and can reach a maximum pressure of 350 bar. Its displacement per revolution is 71 cm³, and it can achieve stepless flow regulation by adjusting the swashplate angle according to system requirements. The pump includes a port pressure sensor, which effectively resists sudden pressure drops and spikes, ensuring stable system operation. Additionally, it offers excellent suction characteristics, low noise levels, and a long service life.
 

Application Areas:

The Rexroth Hydraulic Pump A10VSO71DR/31R-PPA12N00 is widely used in various industrial fields and equipment, primarily in the following areas:
Construction machinery: such as excavators, loaders, bulldozers, etc., used to drive hydraulic motors and cylinders, enabling functions like movement, excavation, and lifting.
Agricultural machinery: in tractors, harvesters, combine harvesters, etc., providing power to hydraulic systems to control operations like steering, plowing, and harvesting.
Industrial equipment: such as injection molding machines, die-casting machines, and presses, where it drives hydraulic cylinders and hydraulic motors to achieve functions such as mold closing, mold opening, and ejection.
Marine and offshore engineering: in hydraulic equipment such as rudder systems, anchor winches, and cranes on ships, it provides stable power output to ensure safe navigation and operational efficiency.
Wind power generation: Used in the yaw system and pitch system of wind turbines, precisely controlling the movement of hydraulic cylinders to achieve yawing and pitch adjustment of the wind turbine blades to adapt to changes in wind direction and speed.
 

Advantages:

High efficiency and energy savings: By adjusting the angle of the swashplate, the flow rate can be infinitely regulated, enabling precise control of the flow rate and pressure of the hydraulic system according to actual requirements, thereby avoiding unnecessary energy waste and improving the overall efficiency of the system. Additionally, the pump's design focuses on optimizing internal structure and flow channels, further reducing energy loss.
High Reliability: Utilizing advanced manufacturing processes and high-quality materials ensures the pump's structural strength and wear resistance. Critical internal components such as pistons and swashplates undergo special treatment, resulting in extended service life. The pump also exhibits excellent contamination resistance, capable of withstanding damage from contaminants in hydraulic fluid to a certain extent.
Excellent dynamic performance: The pump features short control times and rapid response capabilities, enabling it to quickly adapt to load changes and ensure stable operation of the hydraulic system. This makes it particularly suitable for applications requiring frequent starts, stops, or load changes, such as the movement and operation switching of construction machinery.
Diverse control options: The pump offers multiple control modes, including pressure control, flow control, and power control. Users can select the appropriate control mode based on specific application requirements to achieve precise control of the hydraulic system. For example, when constant power output is required, power control mode can be used to match the pump's output power with load demand.
Compact structural design: While ensuring performance, the pump adopts a compact structural design, featuring a small volume and lightweight. This enables it to be conveniently installed in various equipment, saving space while also facilitating lightweight equipment design.
Low noise level: The pump generates minimal noise during operation, providing operators with a more comfortable working environment. This is particularly significant for applications with strict noise requirements, such as indoor operations or equipment with high health standards for operators.
Easy maintenance and servicing: The design prioritizes maintenance convenience, with key components being easy to disassemble and replace. Additionally, the pump is equipped with interfaces that facilitate inspection and maintenance, enabling users to perform routine maintenance and servicing efficiently.
