found in sanitary sewage applications. Since 1939, the name Zoeller has
represented the standard for submersible dewatering and sewage pumps.

been incorporated into this line of heavy-duty submersible grinder pumps.
This Zoeller pump will provide years of trouble-free service when installed
according to the manufacturers' recommendations.
