Sauer Danfoss piston pump 90 series - piston pump

Sauer Danfoss piston pump 90 series - piston pump

Features and advantages:

-Electrical displacement control is a high gain control method: the servo can be driven by a small change in input current control signal

Adjust the main valve core to the fully open position, and then introduce the flow control oil into the servo cylinder.

-The servo valve housing is filled with silicone oil to prevent water vapor from entering and provide vibration reduction, which may prolong the servo valve

Sauer Danfoss piston pump 90 series - piston pumpservice life.

-All specifications of electric displacement control pumps are equipped with dual coil servo valves, and users can choose to use only one of the dual coils

One or both coils can be used (in series or parallel).

-The mechanical limit mechanism inside the servo valve ensures that the control mechanism is not damaged when the electrical input signal changes rapidly.

-The use of components ensures the repeatability accuracy of pump displacement control under the same input signal.

-Using mechanical linkages to achieve closed-loop control of the inclined plate and control mechanism, with the main control valve core in the absence of electrical input control signals

Return to the center position, where both sides of the servo piston are connected to the housing (the inclined plate automatically returns to the center position to ensure system safety).

-After the prime mover stops running, the pump automatically returns to the neutral position.

When the external electrical control signal fails or the oil replenishment pressure is insufficient, the pump automatically returns to the neutral position.
