This model is applied to 27-33T crawler hydraulic excavator, concrete machinery, drilling machine and all kinds of hydraulic open-circuit equipment. Double pumps are connected in series, with negative flow control, positive flow control and constant power control. Double pumps in series can achieve the cross power control, and also independent control of single pump can be achieved by the electric proportional valve to adjust the swash plate's swing angle. It has the characteristics of high power density, strong self-priming ability, long life and low noise and so on.
