Product Overview
The Rexroth A10VO 28 DR/31R-VSC12K01 is a high-performance axial piston variable displacement pump engineered for open-circuit hydraulic systems. Featuring a swashplate design with axial pistons, this pump delivers precise variable displacement control, allowing stepless adjustment of output flow to match system demand. The DR control variant incorporates a pressure regulator (DR = Druckregler), which automatically adjusts displacement to maintain a constant preset system pressure, making it ideal for energy-efficient industrial applications. With a nominal displacement of 28 cm³/rev and belonging to the 31 series, this pump is widely recognized for its robust construction, high power density, and long service life in demanding hydraulic circuits.
