The Model 98 is a high‑performance submersible sump pump engineered for users who need greater flow and higher head than standard 3/10 HP models. Built with cast‑iron motor and pump housings, this pump efficiently dissipates heat to extend motor life and withstand continuous, demanding operation. A corrosion‑resistant powder‑coated epoxy finish adds an extra layer of protection in harsh environments.
At the heart of the Model 98 is a 1/2 HP Permanent Split Capacitor (PSC) motor, delivering strong, efficient performance while maintaining lower operating temperatures. Paired with a non‑clogging vortex impeller, it can pass 1/2‑inch spherical solids and achieve up to 72 gallons per minute with a maximum head of 23 feet, ensuring reliable pumping even during heavy inflow conditions.
Available in multiple cord length options, the Model 98 offers installation flexibility while maintaining compatibility with Zoeller’s popular LED Plug, providing instant visual confirmation of power status. As with Zoeller’s professional-grade lineup, every Model 98 is 100% factory tested, delivering dependable performance from the moment it’s installed.
