Neptune launched the model 5003-S and 5005-S hydraulic diaphragm metering pumps. These accurate, low-volume pumps deliver repeatable flows down to quarts per day, making them ideal in Oil & Gas production, recovery, and in refineries as well. Typical applications include the injection of antifoam agents, corrosion inhibitors and other additives injected at very low volumes but high pressures. The metering pumps can also be used for neat feeding of boiler chemicals.
The pumps feature Eze-Clean valves, which enable the valve cartridges to be removed for cleaning without disturbing the piping. Electronic stroke-length control is available along with explosion-proof models, which can be used in a variety of hazardous environments. The model 5003-S features discharge pressures up to 103 bar, while the 5005-S has discharge pressures up to 207 bar.
