Eclipse for Chemical Dosing

VanLare originally installed peristaltic pumps for Sodium Hypochlorite and its Environmental Service team was in search of a better solution. Peristaltic hose life is unpredictable and inconsistent. These pumps are not leak free so worker safety was also a concern because of inhalation and skin contact with the chemicals. After working with Siewert Equipment, they installed Non-metallic Eclipse pumps. Eclipse sealless design ensures zero emissions of hazardous or regulated chemicals. These pumps have superior chemical resistance. Service is quick and piping and electrical stay in place because of the front pull-out design.

In addition to pumping Sodium Hypochlorite, VanLare installed three Non-metallic Eclipse E25 pumps into the Ferric Chloride station. Ferric Chloride is used for phosphorus removal.
