The Liberty 1100-series duplex sewage ejector package systems are designed for use in multi-unit residential and commercial installations requiring the operational security of a duplex (two pump system). Each unit includes a Liberty LE sewage pump and a 30″ x 36″/110 gallon capacity basin.

The premium Liberty sewage pumps available with each package include pumps from the LE40, LE50, LE70, LE100, LEH100, LEH150, and LEH200 series. The basins themselves are heavy-duty structural foam and include either a 2″ or 3″ discharge. The complete system is factory pre-assembled with the pumps, discharge pipe nipples, and floats pre-mounted in the basin. The floats are tethered to a removable stand pipe/access cover assembly. Features include a 4″ inlet hub with rubber pipe seal, toque-stop pump restraints, and a heavy duty, 1/4″ enamel coated steel cover with two 16″ diameter pump access covers and a 10″ diameter inspection cover with integral stand pipe for float tethering (fiberglass cover available upon request). The cover assembly also includes all necessary bolts and gaskets for mounting the cover to the basin.

Note that these packages are built-to-order and a (separately sold) control panel is required for proper operation. Please use the control panel guide linked below or contact Liberty technical for sizing the correct control panel.
