Zoeller Pumps
Zoeller sump, sewage, effluent and grinder pumps and packaged systems. You may also see the brand written as "Zoller".
Zoeller Pump Company is based in Louisville, Kentucky. It makes pumps for groundwater, raw sewage, septic effluent and pressure-sewer applications.
Zoeller product families
- Sump pumps: for groundwater removal. The Model 53 and 98 are well-known examples.
- Effluent pumps: for graywater and septic systems, such as the N53 and N98.
- Sewage pumps: for raw sewage from below-grade fixtures or buildings.
- Grinder pumps: including the Model 802 and Shark series, for clog-prone waste and pressure sewers.
- Preassembled systems: sump and grinder packages that ship ready to install in a basin.
Selection tips
Identify the liquid (groundwater, effluent or raw sewage). Then calculate the lift and friction losses and choose a model whose curve delivers the flow you need at that head. For septic dosing, follow the system design's dose volume and float settings.

Sizing considerations
- Flow (GPM): estimate peak inflow to the basin or wet well. For effluent dosing, use the dose volume and dosing time set by the system design.
- Total dynamic head (TDH): add the static lift (vertical rise from pump-off level to the discharge point) to friction losses in the pipe, fittings and valves. Choose a pump whose curve crosses your system curve near its best-efficiency range.
- Solids: clear water, effluent, raw sewage or fibrous waste each need a different impeller or cutter. Match the pump's solids-handling rating to the liquid.
- Power supply: confirm voltage and phase (115/230 V single-phase or 208/230/460 V three-phase) and whether start components sit in the pump or the control panel.
- Basin and controls: basin size, pump-down volume, float or level-sensor setup, and a high-water alarm.
- Environment: corrosive or abrasive liquids may call for stainless steel. Classified (hazardous) locations need explosion-proof, approved motors where the code requires them.
- Codes and permits: onsite septic and lift station work is regulated locally. Follow the approved design and local requirements.
