The Zoeller Model X840 is a 2 HP explosion‑proof, auto‑reversing grinder pump engineered for hazardous wastewater applications where flammable gases or vapors are present. FM‑approved for Class I, Division 1, Group C & D locations, the X840 features a hardened stainless‑steel reversing cutter system, dual mechanical seals, and an oil‑filled explosion‑proof motor. Each pump is factory tested to deliver safe, dependable pressure sewer performance in critical environments.

Product Details

The Zoeller Model X840 explosion‑proof grinder pump is designed for the most demanding wastewater applications where both hazardous‑location safety and superior solids reduction are required. Built as part of Zoeller’s XP grinder platform, the X840 integrates FM‑approved explosion‑proof motor construction with true auto‑reversing cutter technology, making it an ideal solution for industrial and infrastructure installations exposed to flammable gases or vapors. With the ability to reach 104 feet of head and 45 GPM.

At the core of the Model X840 is a specially enclosed explosion‑proof motor, engineered to contain any internal ignition event and prevent flame propagation to the surrounding environment. This design enables the pump to meet Class I, Division 1, Group C & D hazardous‑location requirements, allowing safe operation in areas such as refueling facilities, industrial sumps, airports, government installations, and maintenance pits.

The grinder system utilizes a hardened stainless‑steel cutter and disc combined with true auto‑reversing rotation, alternating direction with each cycle to actively pull stringy debris away from the cutter. This significantly reduces roping, minimizes clogging, and extends cutter life compared to single‑direction grinders. Dual mechanical shaft seals and a 416 stainless‑steel motor shaft provide additional protection against seal wear and moisture intrusion.

The pump’s oil‑filled motor design enhances heat dissipation and supports continuous submerged duty, while the heavy cast‑iron motor and pump housings, protected by a corrosion‑resistant epoxy coating, deliver long‑term durability in aggressive wastewater environments. The Model X840 is designed for integration with Zoeller‑approved intrinsically safe control panels, providing proper pump control, reversing logic, and alarm monitoring as required by hazardous‑location installations.

Every Model X840 explosion‑proof grinder pump is 100% factory water‑tested prior to shipment to verify electrical safety, cutting performance, and hydraulic operation. Backed by Zoeller’s proven XP technology, the Model X840 delivers unmatched reliability, safety, and clog resistance in the most severe grinder pump applications.
