7.3 Polymer Injector w/ Integrated Valve
The Pulsafeeder polymer activation system utilizes a special injector with integrated membrane valve
(patent pending). This revolutionary, yet simplistic valve does not have springs or seats to foul. In fact
there is only one elastomeric moving part that is easily replaceable and requires no tools. Simply slide the
old sleeve off the end of the quill and slide on a new one (some lubricant will help with this). The quill
has a recessed area for the sleeve with holes in it. Make sure the new sleeve is completely within the
recessed area and that the sleeve completely covers the injection holes.
