Model 915 Grinder Package System

Product Details

The Zoeller Model 915 Grinder Package System is engineered to deliver a reliable, preassembled solution for wastewater applications where solids reduction is required. Designed for residential and light commercial use, the Model 915 utilizes a compact grinder pump to macerate solids, reducing the risk of clogging and allowing the system to compete with traditional sewage ejector installations.

Each Model 915 system is shipped factory assembled with a 1/2 or 1 HP grinder pump and is available with snap‑action (integral) or piggyback mechanical float switch designs, depending on the configuration selected. These options allow installers to match the system to site‑specific operating preferences while maintaining reliable automatic operation.

The package is offered with 18″ × 30″ or 24″ × 24″ basin sizes, using approved polymolded, polyethylene, or fiberglass basin materials. To accommodate deeper or outdoor installations, the system supports approved basin extensions and risers, allowing flexibility across new construction, retrofit, and replacement applications.

Installation‑friendly enhancements include a removable float tree, molded torque stops, and an anti‑flotation device to secure the pump during operation. The 24″ x 24″ features a clear construction cover included to protect internal components during rough‑in and masonry work. Optional high‑water alarms and Wi‑Fi‑enabled monitoring solutions, provide additional protection and notification.

Every Model 915 grinder package is 100% factory tested prior to shipment, ensuring dependable operation upon installation. Backed by Zoeller’s grinder pump expertise, the Model 915 delivers a compact, clog‑resistant solution for wastewater applications where a traditional sewage ejector may not be sufficient.
