Radial Piston Pumps – 2R
The Polyhydron 2R series consists of rugged, oil-immersed radial piston double pumps designed for high-pressure industrial hydraulic systems. These pumps feature a valve-controlled design with a fixed output per revolution, allowing for bi-directional shaft rotation without affecting performance.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
