About Little Giant Effluent Pumps

Effluent pumps by Little Giant are commonly installed in septic tanks to pump effluent waste also known as “grey water”. Different models are capable of processing various solids ranging in size from 3/8” to 2”. 6 and 10 series also includes high-temperature models, capable of handling liquid with up to 200˚F. 14EH, 16EH and 20E series are high-head effluent pumps, designed to pump waste at higher elevations and larger distances. ES33, 50 and 60 are high-efficiency, energy-saving models.
Automatic pumps come with either a diaphragm, snap-action (vertical) float or wide angle float switches which regulate the pumps’ operation and have model-specific On and Off ranges.
