An internal control system for parallel pump fluid pumping systems. The control system acts to open a low-pressure pathway receiving the discharge from at least one of the pumps in response to internally sensed outlet requirements. The open pathway results in recirculation of low-pressure pumped fluid through a portion of the system while the outlet is supplied from another of the parallel pumps. The control system operates by sensing pressure from various points within the fluid system.
