YUKEN 50T series quantitative vane pump model and parameters
I. Series Overview
The YUKEN 50T series is a low-noise, pressure-balanced structure fixed displacement single-stage vane pump with low shaft load and long service life. It is widely used in lubrication systems, cooling systems, light-load hydraulic circuits, precision machine tools and other scenarios. It can be used as a low-pressure vane pump in high-pressure systems, and can also be composed of double pumps (such as 5050T, 50150T) or combined pumps (such as 5050ST, 50150ST).
