Product description
PZL Series Liner ejector
1. Introduction
1.1 purpose
The ejector is a kind of equipment that sucks and ejects another kind of low-pressure fluid by the negative pressure produced by the high-pressure fluid (generally water) formed by the nozzle, and has the mixing function. In water treatment, liner injector is used to dilute and transport hydrochloric acid regeneration solution.
1.2 model significance
