APPLICATIONS

1.  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 items normally found in sanitary sewage 

applications.

2. Zoeller 7011, 7012 and 7013 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 7011, 7012 and 7013 can be installed in a 

Prepackaged Job Ready System or may be used in a 

Field Assembled basin package.  Pages 6 and 8 show 

a couple of Prepackaged Systems. Field Assembled 

Systems are discussed on pages 3 and 4.

4.  Zoeller 7011, 7012 and 7013 Grinder Pumps can be 

retrofitted  to  existing  positive  displacement  pump 

installations.

*

Zoeller Company does not recommend a simplex station on anything over two homes in order to maintain continuous service during unusual  

conditions.

Recommended Limits of Application 7000 Series Grinder Pumps

These recommended application limits are for pump stations pumping to a gravity main.  Low-pressure pipe systems should be designed with a 

pump located at each house.  For applications where a lift station would handle between 15 and 60 homes, consider the 71 Series grinder pump.  

For applications where a lift station would handle more than 60 homes, a solids handling type pump should be considered.
