ApplicationHOMA CH 432 and CH 436 stain-less steel submersible drainagepumps are suitable for pumpingcorrosive, abrasive or chemicallyaggressive liquids, drainage wateror chemicals*) containing softsolids up to 13/4 diameter. Theyare used in various domestic, indu-strial or municipal applications.

Typical Fluids Handled are: Drainage water Effluent with soft solids Chemically aggressive liquids* Liquids to 140 F can be handled

intermittently*

CH Series Pumps are typicallyused in: Industrial and commercial

drainage Industrial chemical waste or

effluents Optional Factory Mutual (FM)

label for Class I, Div 1 EX construction.

* According to specific chemicalresistance of used materials
