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 V20F Series is based on the V20 pressure-balanced vane-pump platform and provides flange, shaft-extension, and port combinations for heavy-duty vehicle integration. It combines high-load oil-supply capability, compact installation, and series-based selection.
The appropriate model can be selected according to vehicle steering load, engine interface, and controlled-flow requirements for power-steering systems in heavy-duty trucks and engineering vehicles.

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