Congratulations on the purchase of the Zoeller X71 Series sub-
mersible grinder pump.
This pump has been constructed in compliance
with CSA testing. These requirements enable the unit to be listed as an
explosion proof pump rated for use in Class I, Division 1, Group C & D loca-
tions.
Zoeller grinder pumps are designed for grinding and pumping
sanitary sewage from submersible lift stations. The pump is intended
to grind and pump reasonable quantities of disposable diapers, sanitary
napkins, paper towels, rubber materials, plastics, cigarette butts and
other items normally found in sanitary sewage applications. For over
sixty years since 1939 the name Zoeller has represented the standard
for submersible dewatering and sewage pumps. The same high quality
workmanship and easy maintenance design has 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.
This manual incorporates the installation, operation, maintenance,
and service instructions into one document to aid in the ownership of a

manual before installing the product. Follow the steps and procedures
listed on ZM1074 for a proper start-up and warranty protection. Many
