Product Description

 

General Introduction

The A10VSO axial piston variable pump is designed for a wide range of hydraulic systems, featuring high performance and reliability. It is suitable for hydrostatic drives in open circuits, with a variable displacement design that enables precise control of the hydraulic fluid flow rate, thereby improving efficiency and performance in various applications.
 
Structural Characteristics
It adopts an axial piston swash-plate structure. The 31- series (sizes 18 to 140) pumps have a wide range of controllers and actuators. Pumps of the same size can form a combined pump through a through - shaft structure (except for size 10).
 
Performance Characteristics
- Pressure Rating: It operates at a nominal pressure of 280 bar and a maximum pressure of 350 bar, which enables it to handle high - pressure applications effectively.
- Flow Adjustment: The flow is proportional to the drive speed and displacement. By adjusting the swash - plate angle, the flow can be infinitely varied, allowing for accurate control of the pump's output.
- Excellent Suction Characteristics: The pump's design ensures excellent suction performance, which helps maintain efficiency and performance under various operating conditions.
- Low Noise Level: It operates with a low noise level, making it ideal for applications where noise reduction is important.
- Axial and Radial Load Capacity: The drive shaft can bear considerable axial and radial loads, which improves the pump's durability and operational reliability.
- Versatile Control Forms: To meet different application requirements, there are various control forms, including pressure - only control, pressure - and - flow control, electro - hydraulic control, etc.
