The Zoeller Model EX4294 is a heavy-duty, nonautomatic 1−1/2 HP effluent pump certified as explosion-proof for hazardous environments (Class 1, Division 1, Groups C & D or Class 1, Zone 1, Groups IIA & IIB). It requires an intrinsically-safe control panel and floats for operation. Engineered for reliable performance in demanding sewage and dewatering applications, the pump is designed with a vortex impeller that can pass 2" spherical solids freely, which helps minimize clogging and downtime. Its durable construction is built to last, featuring cast iron motor housing, pump housing, and base, along with corrosion-resistant stainless steel hardware for superior resilience. To guarantee quality, every unit is rigorously submerged and tested to its performance curve, delivering peace of mind right out of the box.
