This series of vane pumps features excellent flow-speed characteristics, maintaining a constant output flow rate even as rotational speed increases. They are widely used in power steering systems for light-duty trucks and passenger vehicles.
The YBZ5 Series vane steering pump is intended for vehicle power-steering applications and offers multiple controlled-flow, pressure, rotation, and interface combinations. Models can be selected according to vehicle steering load and engine-layout requirements.
Integrated pressure protection helps prevent system overload, while the compact construction and diverse drive interfaces facilitate platform-based vehicle integration.
