Model 841 Grinder Pump

Product Details

The Zoeller Model 841 Shark® grinder pump is engineered for pressure sewer applications where robust solids reduction and dependable, single‑direction grinder performance are required. Designed as the non‑reversing companion to the Model 840, the 841 delivers powerful grinding capability while maintaining a straightforward, panel‑controlled operating design.

At the core of the Model 841 is a 2 HP oil‑filled motor, providing the torque necessary to grind and pump tough wastewater materials through 1‑1/4″ pressure piping. With the ability to reach 125 feet of head and 54 GPM. The oil‑filled motor design ensures effective heat dissipation, allowing the pump to operate cooler during extended duty cycles commonly encountered in pressure sewer systems.

The grinder assembly utilizes a hardened stainless‑steel cutter and cutting plate, designed to aggressively reduce solids and maintain consistent hydraulic performance. All major structural components—including the motor housing and pump housing—are constructed from cast iron and protected with a corrosion‑resistant powder‑coated epoxy finish to withstand harsh wastewater environments.

The Model 841 is a nonautomatic grinder pump, intended for integration with external simplex or duplex control panels. This configuration allows system designers and installers to tailor float control schemes and alarm functionality to specific application requirements. Dual mechanical shaft seals, stainless‑steel hardware, and heavy‑duty bearings further reinforce the pump’s durability and reliability over long service intervals.

Every Model 841 grinder pump undergoes 100% factory water testing prior to shipment, ensuring verified cutting performance, electrical integrity, and hydraulic output from day one. Backed by Zoeller’s Shark® grinder technology and an 18‑month limited warranty, the Model 841 provides a dependable solution for residential and light commercial pressure sewer installations where simplicity and durability are paramount.
