REXROTH AL A10VO 28 ED72/31L-VSC12N00P / R902488269

Product Overview

The Rexroth AL A10VO 28 ED72/31L-VSC12N00P (Material Number: R902488269) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for open-circuit hydraulic systems. Featuring a swashplate design, this pump delivers precise, infinitely variable displacement control by adjusting the swashplate angle, enabling accurate flow matching to system demand. With a nominal displacement of 28 cm³/rev and a size 28 frame, the A10VO series is renowned for its high power density, fast response characteristics, and long service life in demanding industrial environments. The ED72 control variant provides electro-hydraulic proportional displacement control with integrated pressure compensation, making it ideal for applications requiring both precise flow modulation and reliable pressure limiting. This pump serves as a critical power source in hydraulic systems across injection molding, metallurgy, and heavy machinery applications.
