This centrifugal end suction pump incorporates a cast iron casing with a bronze impeller and a stainless steel shaft protected by a bronze shaft sleeve. The assembly utilizes a dry shaft design rated for 125 PSI without a wear ring to prevent fluid contact with the internal shaft materials. A ceramic seat and EPT rubber mechanical seal component manages fluid containment during operation.
Operating at 20 HP, the Premium Efficiency TEFC motor runs at 3450 RPM and integrates Aegis Grounding with a 380-460V / 3PH power supply, resulting in a DOE PEI of 0.46. The 'S' in the SFI series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a fused disconnect without bypass and holds an enclosure NEMA 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
