Chemical feed, matched to the dosing point — not the catalog page

The terms are often used interchangeably, but a metering pump is specifically engineered for high-accuracy, repeatable dosing at a precise rate — the distinction matters when a process requires tight concentration control (like pH neutralization) versus simple chemical transfer, where accuracy tolerance is looser.

The same Material Specification discipline as any wetted equipment — pump head, diaphragm, O-rings, tubing, and injection fittings all need to be individually confirmed compatible with the actual chemical, concentration, and temperature, not assumed compatible because the pump is marketed for 'chemical feed' generally.

Per the Zero-Guesswork Instrumentation gate, flow verification confirms the system is actually moving liquid, not just that the motor is running — a metering pump can run electrically while losing prime or dosing incorrectly, and a control system that only monitors motor status won't catch that failure mode.

Yes — duty/standby sequencing, interlocks (e.g. tank low-low level), and alarm levels define what the system does when a fault condition occurs, not just what it does under normal operation. A dosing skid without a defined control response to an empty source tank is a real, avoidable failure mode.
