RoHS Compliance: Ensures the pump does not contain hazardous materials.

Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.

FAQ

1.How does the variable displacement work?

• Core Mechanism: The pump uses a swashplate to control the stroke of the pistons. Changing the swashplate angle directly alters the volume of oil displaced per revolution.

• Control Modes: Depending on the selected control type (LR, DR, EP, HD), external signals or system pressure adjust the swashplate position.

  For power/load-sensing control: The pump automatically reduces displacement when system pressure rises, maintaining constant power output and preventing engine overload.

  For pressure cut-off control: Displacement is reduced to near zero once the set pressure is reached, avoiding pressure spikes and energy waste.
  
  Operational Benefit: This on-demand adjustment allows the pump to deliver only the required flow for the system, improving overall efficiency and reducing heat generation under partial-load conditions.
