This base-mounted end suction pump is constructed with a cast iron casing, a bronze impeller, and a stainless steel shaft paired with a bronze shaft sleeve. The dry shaft design prevents contact between the circulating fluid and the shaft, which contributes to an operational rating of 125 PSI without a wear ring. A mechanical seal, integrating a ceramic seat and EPT rubber components, provides the necessary containment for the assembly.
Powered by a 15 HP premium efficiency TEFC motor, this assembly operates at 1750 RPM and incorporates Aegis grounding within a 200-230V 3PH power supply, resulting in a DOE PEI rating 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
