Brand: Liberty Pumps
Part#: 1102-LE51M-AE
Liberty 1102/LE51M-AE is a duplex sewage ejector system with a 30" x 36", 110-gallon basin, (2) LE51M sewage pumps and AE21L=3 control panel with integrated alarm. Discharge and vent pipes are 2". The system is factory-assembled and is ready for installation - simply connect the piping and wire the control panel (pumps, discharge pipe and floats are pre-installed inside basin).
Liberty 1100 series is a true duplex system with Lead/Lag pump operation, where Lag (secondary) pump can engage if the Lead (primary) pump is not capable of removing high volume of incoming wastewater - allowing for both pumps to run at the same time.
AE series control panel is packed with features and can be customized to fit project needs - see the control panel product listing for details.
