QUANTM's electric diaphragm design is self-priming and seal-less by construction — removing the mechanical-seal failure point a centrifugal transfer pump would introduce on a wastewater neutralization dosing loop.
A wastewater pretreatment neutralization loop lives or dies on dosing accuracy, not raw flow — QUANTM's stall-under-pressure behavior removes the need for a separate pressure-relief controller, which is why it paired cleanly with the closed-loop PLC dosing architecture specified on this job.
