Pump Design Distinctions

Wilo EMU pumps are specifically engineered to protect motor components from both heat and moisture. Exclusive Thermo-Centric™ engineering, which effectively transfers heat away from all critical components, significantly reduces the potential for heat-related damage. Thermo-Centric™ engineering ensures the Wilo EMU submersible and dry-pit pumps operate at or near ambient temperatures, even in long-term continuous operation. Also, unique long-life silicon carbide seals provide absolute protection from moisture intrusion and deliver operational cycles that are 15 to 20 times longer than those of ordinary carbon-ceramic seals.
