It is in combination with two variable pumps, a common drive shaft is used.由两个变量叶片泵结合一体，使用共同的驱动轴。
It is low-noise, small in size, high in efficiency, long in service life and fast; the flow and pressure can be adjusted , and it is most suitable for small and light-weight equipment such as working machine and shoe-making machine.
静音、小型化、效率高、寿命长、应达快；流量和压力可以随意调整，最适合用于工作机械及制鞋机等小型轻量化设备。
