2.  Zoeller Grinder Pumps can be installed in new applications or as 

a direct replacement for other grinder application of like size and 
capacity.

3.  Refer to the Zoeller models 7020 and 7021 when retrofitting  existing 

positive displacement pump installations.

Applications

1.  Zoeller Grinder Pumps are designed for grinding and pumping 

sewage from single family residential and commercial duty sewage 
pump stations.  The pump is intended to grind and pump reasonable 
quantities of items normally found in domestic sewage.

*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.
