These recommended application limits are for pump stations pumping to a gravity main. Low-pressure collection systems should be designed with
a pump located at each house. For applications where a lift station would handle more than 2 homes, consider the 840 or 71 Series grinder pump.
For applications where a lift station would handle more than 60 homes, a solids handling type pump should be considered.

1. Zoeller Progressing Cavity 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 items
normally found in sanitary sewage applications.
2. Zoeller 810 and 815 Progressing Cavity Grinder Pumps can be
installed in new applications or as a direct replacement for any grinder
application of like size and capacity. Some rail system retrofit kits are
available.
3. The 810 and 815 can be installed in a Prepackaged Job Ready System
or may be used in a Field-Assembled basin package. Page 5 shows
a couple of the Prepackaged Systems. Field Assembled Systems are
discussed on page 4.
4. Zoeller 810 and 815 Grinder Pumps can be retrofitted to existing
positive displacement pump installations.
