Product Details

The Zoeller Model X641 Explosion‑Proof Sewage Pump is purpose‑built for wastewater applications in hazardous locations where safety and reliability are paramount. Designed for industrial, municipal, and infrastructure installations, the Model X641 combines Zoeller’s proven sewage pump construction with an explosion‑proof motor enclosure to meet the demands of environments containing flammable gases or vapors. With the ability to reach 39.5 feet of head and 420 GPM on single phase models. With a higher head of 44 feet of head and 460 GPM on three phase models.

At the core of the Model X641 is a specially enclosed explosion‑proof motor, engineered to contain any internal ignition event. Should vapor ignite inside the motor, the enclosure prevents flame propagation and ensures that surrounding vapors cannot be ignited. This design allows the pump to be used in Class I, Division 1, Groups C & D Rated Class I, Zone 1, Groups IIA & IIB hazardous locations, including maintenance pits, industrial sumps, refueling areas, government facilities, and other regulated environments.

The pump’s cast‑iron motor and pump housings, protected by a corrosion‑resistant epoxy coating, provide durability in harsh sewage and industrial conditions. An oil‑filled motor design promotes effective heat dissipation, supporting long service life in demanding applications. The Model X641 is available in nonautomatic configurations, allowing flexibility for direct installation or integration with Zoeller‑approved explosion‑proof control panels featuring intrinsically safe relays and monitoring systems.

Every Model X641 Explosion‑Proof Sewage Pump is 100% factory water‑tested prior to shipment to verify electrical integrity, hydraulic function, and compliance with hazardous‑location requirements. Backed by Zoeller’s decades of experience in explosion‑proof pump engineering, the Model X641 provides peace of mind and dependable performance where conventional sewage pumps cannot be safely used.

Features and Benefits
  • Oil-filled motor and cast iron motor housing for optimal heat dissipation which prevents the pump from overheating
  • Nonautomatic pump that will require a control panel to control the pump's on / off level
  • Corrosion resistant ductile iron semi-open impeller to allow free passage of 2-1/2" spherical solids which prevents clogging and increases reliability
  • Stainless steel screws, handle, and hardware to prevent rust and corrosion
  • Powder-coated epoxy finish provides corrosion-resistance and extends the life of the pump in harsh environments
  • 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
