The Neptune 5000 Series Low-Volume Chemical Metering Pump is built to deliver very low flows that are repeatable and accurate, ranging down to quarts per day. Discharge pressures are higher than mechanical metering pumps. 

These pumps are especially well-suited for oil/gas production, oil recovery, and refineries. Typical applications include the injection of antifoam agents, corrosion inhibitors, and other additives injected at very low volumes but high pressures. These pumps are also used for neat feeding of boiler chemicals.

The EZE-CLEAN™ valve cartridges can be removed for cleaning without disturbing piping.
