These 110 to 120V effluent pumps are used to drain treated water containing small solids from septic tanks and out to a drain field. They are compatible with most standard U.S. residential electrical wall outlets and have a Type A (two prongs, ungrounded) or Type B (three prongs, grounded) power cord plug.

These single-phase 200 to 240V effluent pumps use a higher voltage that allows for larger motors that require less current than lower-voltage motors. They are used to drain treated water containing small solids from septic tanks and out to a drain field.

These three-phase 220 to 480V effluent pumps have three-phase motors that are more efficient than one phase, and they use a higher voltage that allows for larger motors that require less current than lower-voltage motors. They are used to drain treated water containing small solids from septic tanks and out to a drain field. Three-phase pumps require a control panel.
