Liberty's 250-series effluent pumps are designed to move effluent water out of a water system. Effluent or graywater is simply all the water that is used throughout the day which may contain solids, such as shower water, (the exception is wastewater or sewage). Effluent pumps are typically in applications that involve transporting graywater out of laundry tray systems, septic tanks, or sump pits. Each Liberty 250-series pump features an epoxy powder coated finish, unibody casing, and can handle 1/2" solids. All pumps operate in single phase power and have a maximum thermal overload temperature of 221°F. A special 3-year warranty is attached to this series. The Liberty 250-Series pumps can also be used as sump pumps.
