What “Variable Frequency Drive Pump Control and Energy Saving” means on an RFQ
Pump VFD energy saving comes from affinity-law speed reduction on variable flow — only after you confirm the system curve actually allows lower RPM.
RFQ data that locks voltage and power class
RFQ needs pump curve or rated head/flow, static vs friction head split, and whether pressure or flow is the controlled variable.
Control functions that change field behaviour
Use PID on a real transducer for constant pressure; skip fancy macros until the sensor scaling and sleep/wake levels are proven.
Site, EMC and protection notes
Cabinet heat, transducer impulse lines and motor cable length decide whether the energy saving survives the first summer.
How Boray series map to this topic
FS200 / FS300 for constant-pressure skids; BR110 when the pump is one of several industrial loads on a general vector platform.
