VARIABLE DISPLACEMENT PUMP WITH FLOW DELIVERY TO DIFFERENT SYSTEMS WITH DIFFERENT PRESSURE SCHEDULES
DRIVE
October 1, 2025
A system includes a variable displacement pump (VDP) (102) with a pump inlet (104) and a pump outlet (106). The VDP is configured to receive a flow at the pump inlet at a first pressure and to outlet a flow from the pump outlet at a second pressure elevated relative to the first pressure. The VDP includes a variable displacement mechanism (107) configured to vary the second pressure. A controller (112) is operatively connected to a pressure sensor and to the variable displacement mechanism for control of the VDP. An output splitter (114) is configured to split flow from the pump outlet to a first outlet branch and to a second outlet branch for supplying two different systems each having a different pressure schedule. The output splitter is operatively connected to the controller, which is configured to control the output splitter to regulate pressure in both of the first and second outlet branches.
