Rexroth Replaces A2FO Series Axial Piston Model A2FO90/61R-PAB05 Plunger Pump Assembly
Product Description
It features an oblique shaft design, which provides high transmission efficiency and effectively reduces energy loss. This design allows for a more compact and efficient power transfer within the pump. The pump is equipped with an axially tapered piston rotor group, which is specifically designed for open circuit hydrostatic transmission. This design enables the pump to handle high pressures and provides smooth and reliable operation. The displacement of the A2FO series pumps typically ranges from 5 to 130 cm³/rev, with specific models available in various sizes such as A2FO5, A2FO10, A2FO12, and so on, up to A2FO1000. This wide range of displacements allows the pump to be customized to meet the specific flow requirements of different applications.
Piston pump advantage
