HI 7.8 – Controlled Volume Metering Pump Piping Guideline
This guideline applies to controlled volume metering pumps, specifically those with pulsating flows. Types of positive displacement pumps include, but are not limited to, hydraulic-coupled disc diaphragm, hydraulic-coupled tubular diaphragm, mechanical-coupled disc diaphragm, packed piston, and plunger. This document covers typical piping and accessories upstream and downstream from the pump(s).
