Liberty Pumps AE-Series Duplex Pump Controls

Liberty Pumps AE-Series Duplex Pump Controls

Important Information

AE-Series duplex panels control two 1-phase or 3-phase pumps in water and sewage installations.

This panel includes a new innovative duplex controller for pump control, alternation and alarm; including float switch status LEDs, control/alarm power ON/OFF switch with LED indicator, pump run LEDs, HOA switches, pump lead/lag selector switch, auxiliary contacts and more.

The control panel features built-in lag pump delay time, pump failure detection, and float switch out-of sequence notification. In addition, there are user-selectable field programmable operations: alarm steady-state or flashing; alarm auto reset or manual reset; pump failure notification.

35′ and 50′ cord lengths available. Add “-3” or “-5” suffix to model number. Example: AE21L=3-3 for 35′ cord.
NOTE: AE-Series panels come with variable amp ranges and must be ordered with the correct matching full load amp to that of the pump(s) being used. Use the chart above to select the proper amp range or consult the factory for technical assistance.
3-phase panels come equipped with thermal overload protection that must be properly sized to the pump’s full load run amps. Please consult factory for proper panel selection. All 3-phase “standard” panels come with NEMA 4X enclosure.
* AE24HC=3-3 includes start/run capacitors and start relay for use with LSG202M-C and LSGX202M-C models.
** Capacitor kit required. (Purchased separately.)

Liberty Pumps can customize a panel to your specific pump needs.
