If you're looking for a small grinder pump system for a septic application, you're likely dealing with a situation where wastewater needs to be pumped from a lower elevation (like a basement bathroom or remote fixture) to a septic tank or sewer line. Here’s what you need to know:
Grinder Pump: Designed to macerate solids (toilet waste, paper, etc.) into a slurry before pumping. Ideal for septic systems where solids need to be broken down.
Sewage Ejector Pump: Handles liquids and small solids but doesn’t grind them finely. Better for gray water or light-duty use.
Some reliable small grinder pump systems include:
Liberty Pumps LG50 – Compact, ½ HP, handles residential waste.
Zoeller M267 – ¾ HP, durable for septic applications.
E/One Grinder Pump Systems – Low-pressure septic systems with grinders.
Goulds Grinder Pumps (like GS series) – Heavy-duty for septic and sewage.
Most grinder pumps come with an integrated basin (drum), but if you need a separate one:
Polyethylene basins (e.g., Zoeller Preassembled Packages).
Concrete or fiberglass tanks for buried systems.
Small Simplex Systems (single-pump setups) for residential use.
Flow Rate – Match the pump’s GPM (gallons per minute) to your needs.
Head Pressure – Ensure the pump can handle vertical lift.
Septic-Safe – Confirm the pump can handle solids common in septic systems.
Alarm & Controls – Look for systems with high-water alarms.
Place the pump in an accessible location.
Ensure proper venting to prevent odors.
Use check valves to prevent backflow.
