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 V20NF Series uses a pressure-balanced vane design and offers multiple combinations of displacement, controlled flow, pressure, and mounting interface for heavy-duty vehicles. The series can be matched according to engine speed and steering load.
The product combines stable oil supply, compact construction, and multi-platform adaptability, making it suitable for heavy-duty trucks, engineering vehicles, and special-purpose vehicles.

TECHNICAL FEATURE
01. Open-type design; currently available shaft-end connection types include splines, flat ends, etc. The port orientation, specifications, and shaft-end connections can also be customized according to user requirements.
02. The pump incorporates a flow control valve to maintain constant output flow; it is also equipped with a safety valve to prevent hydraulic system overload—this is an internally feedback-controlled design.
03. Three-piece construction
