Blue-White states diaphragm metering pumps require priming before startup — unlike the company's peristaltic FLEXFLO line, which is self-priming; skipping this step on a CD-series install is a real, vendor-flagged operational tradeoff, not an assumption to skip past.
A diaphragm metering pump that isn't primed on startup doesn't underdose, it doses nothing — a silent zero rather than a slow leak. Blue-White built DFD into the CD-series specifically because that failure is common enough to engineer around, and James Riggins treats priming verification as a commissioning checklist item, not a given.
