Model 284 Sewage Pump

Product Details

The Zoeller Model 284 is a heavy‑duty sewage ejector pump engineered for demanding commercial, municipal, and multi‑unit wastewater systems where durability and reliability are critical. Built from robust cast‑iron components—including the pump housing, motor housing, and vortex impeller—the 284 is designed to withstand continuous exposure to sewage, solids, and corrosive environments.

At the core of the Model 284 is a high‑performance, oil‑filled motor that maintains optimal operating temperatures, even during extended duty cycles commonly encountered in lift stations and high‑volume wastewater systems. The cast‑iron vortex impeller is capable of passing 2‑inch spherical solids, ensuring smooth, non‑clogging operation and reducing maintenance downtime in systems with wipes, rags, and heavy debris loads. With the ability to reach 35 feet of head and 179 GPM.

The Model 284 is available in both automatic and nonautomatic configurations. Automatic versions utilize Zoeller’s reliable snap‑action float switch system, complete with a protective float guard to ensure consistent operation in debris‑filled pits. Single phase nonautomatic models can be easily paired with piggyback float switches to enable automatic cycling or integrated into engineered control‑panel systems where custom level control is required.

For enhanced protection in demanding wastewater applications, the 284 supports tandem shaft seal configurations, offering dual mechanical seals that extend motor life and provide additional safeguards against infiltration and seal wear.
With its rugged construction, clog‑resistant hydraulics, and exceptional thermal performance, the Model 284 is engineered to deliver long‑term reliability in commercial sewage ejector systems, municipal lift stations, and high‑capacity wastewater environments. Every pump undergoes 100% factory water‑testing, guaranteeing performance to published curves.

Features and Benefits

• Oil-filled motor and cast iron motor housing for optimal heat dissipation which prevents the pump from overheating
• Available in automatic and nonautomatic versions. A nonautomatic Model 284 becomes a fully automatic unit when paired with a piggyback float switch; nonautomatic versions without a piggyback require external float controls or a control panel for activation.
• Corrosion resistant cast iron vortex impeller to allow free passage of 2" spherical solids which prevents clogging and increases reliability
• Automatic configurations include protected float mechanisms for reliable switching; nonautomatic versions do not include a float guard.
• Automatic models utilize Zoeller’s snap‑action float switch system. Nonautomatic units rely on piggyback float switches or panel‑controlled systems.
• Powder-coated epoxy finish provides corrosion-resistance and extends the life of the pump in harsh environments
• Stainless steel screws, handle, and hardware to prevent rust and corrosion
• 100% Factory Tested - every pump is submerged in water and tested at the factory to ensure that it performs as expected when you receive it
• Comes with a 1-year limited warranty giving you protection over your investment and the peace of mind you expect in a quality product
