A11V Axial Piston Variable Pump

Updated: 2026-07-22

Overview

The A11V axial piston pump is a critical component in hydraulic systems, renowned for its durability and performance. Developed for heavy-duty applications, it is widely used in industries requiring precise fluid power control. The pump's design allows for variable displacement, making it adaptable to varying load conditions. Manufactured by leading hydraulic equipment producers, the A11V series is known for its efficiency and reliability. Its modular design facilitates easy integration into different hydraulic systems, catering to both mobile and stationary applications. The pump's robust construction ensures long service life even under demanding operating conditions.

Structure and Working Principle

The A11V pump consists of a rotating group of pistons arranged in a circular pattern within a cylinder block. As the block rotates, the pistons reciprocate, drawing in and expelling hydraulic fluid. The swashplate angle determines the displacement volume, allowing for variable flow rates. Key components include the drive shaft, cylinder block, pistons, swashplate, and control mechanism. The pump's efficiency is enhanced by precision machining and high-quality materials, reducing internal leakage and wear. The variable displacement feature is controlled via a hydraulic or electronic system, enabling real-time adjustments to meet operational demands.

B2B Procurement Guide

When procuring A11V pumps, evaluate the specific requirements of your hydraulic system, including flow rate, pressure range, and control options. Ensure compatibility with existing components to avoid integration issues. Source from reputable manufacturers or authorized distributors to guarantee genuine parts and reliable performance. Consider after-sales support, warranty terms, and availability of spare parts. Bulk purchases may offer cost advantages, but verify lead times to align with project schedules. Custom configurations may be available for specialized applications.
