Model 912 Sewage Package System

Product Details

The Zoeller Model 912 Sewage Pump Package System is engineered to deliver a reliable, job‑ready solution for sewage ejector applications where plumbing fixtures are located below the existing sewer line. Designed for residential and light commercial installations, the Model 912 ships factory assembled to reduce labor time and improve installation consistency.

Each Model 912 system is available in simplex or duplex configurations using 4/10 HP or 1/2 HP automatic sewage ejector pumps. Automatic operation is provided by either snap‑action (integral) float switches or piggyback mechanical float switches, depending on the pump model selected. Duplex systems incorporate alternator controls that balance run time between pumps to extend service life.

The standard package includes a 24″ × 24″ poly basin with 41‑gallon capacity, optimized for shallow burial and indoor installations. To accommodate deeper or outdoor installations, the system supports approved basin extensions and risers, as well as 18″ × 30″ basin configurations using compatible PSF or fiberglass basin components.

Installation‑focused enhancements include a removable float tree, molded torque stops, and an anti‑flotation device to help secure the system once installed. The 24″ x 24″ basins include a clear construction cover that is shipped with each package to protect internal components during rough‑in and masonry work.

Optional high‑water alarms and Wi‑Fi‑enabled monitoring solutions, are available to enhance system protection and notification. Each Model 912 package is 100% factory tested prior to shipment, ensuring dependable performance out of the box.
