Neptune Corporation Stops

Corporation Stops with Injection Quills are used for injecting chemicals pumped by metering pumps into tanks, mains, cooling towers and process systems. Because quills extend into the center of the stream, they provide more rapid, uniform dispersion of injected chemicals.

Corporation Stops can be mounted to a “hot tap” which will allow an injection quill to be inserted or removed without having to drain or shut down the system.

High-Pressure Injection Quills are used to inject chemicals pumped by metering pumps into the turbulent flow zone of high-pressure water or steam lines.
