This series of pumps achieves high operating pressure within a compact design, ensuring a high power-to-weight ratio and low installation costs, and is widely used in power steering systems of heavy-duty trucks.
The V20 Series vane steering pump uses a pressure-balanced design with radially opposed inlet and outlet pressure chambers to reduce unbalanced loading. Optimized vane, cam-ring, and inlet-passage design makes the pump suitable for higher speeds and greater steering-assist demand.
The series is intended for heavy-duty trucks and engineering vehicles. Models can be selected according to flow, pressure, shaft extension, and interface requirements.
