A2FO80 Axial Piston Fixed Hydraulic Pump
- Product Details
- Product Model
- FAQ
The A2FO80 is a compact, high-performance axial piston fixed displacement hydraulic pump, typically used in open-loop hydraulic circuits. It operates on the swashplate principle, where a rotating cylinder block with several pistons drives fluid flow. As the block rotates, the pistons reciprocate within their bores against a fixed-angle swashplate, creating a constant volume of fluid per revolution. The A2FO80 is designed for high working pressures (often up to 350 bar or more continuous) and high speeds, offering excellent volumetric and overall efficiency. Its key features include a robust construction, low noise levels, and long service life, making it suitable for demanding mobile and industrial applications like construction machinery, material handling, and agricultural equipment. The "80" in its designation commonly refers to its nominal displacement of 80 cm³/rev. Its fixed displacement design means the flow output is directly proportional to the input shaft speed, providing a simple and reliable solution for constant flow requirements.

Q1: Why is the A2FO80 pump classified as having a "fixed displacement"?
A1:The A2FO80 hydraulic pump is classified as "fixed displacement" because the angle of its swashplate is not variable. This results in a constant volume of fluid being displaced per shaft revolution, making the output flow dependent solely on the pump's speed.
Q2:In which specific types of machinery is the A2FO80 pump commonly found?
A2:The A2FO80 hydraulic pump is commonly found in heavy-duty mobile machinery like excavators and wheel loaders, as well as in various industrial systems such as presses and material handling equipment, where constant hydraulic flow is required.
Q3:How to purchase an A2FO80 hydraulic pump?
A3:You can click on the right sidebar or the contact information in the top bar to contact us to purchase. You can do so via email, form, WeChat, WhatsApp, or other methods.
