This base-mounted end suction pump is constructed with a class 30 cast iron casing and integrally cast mounting feet. It utilizes a bronze impeller and a replaceable bronze shaft sleeve mounted on a stainless steel shaft. The dry shaft design prevents contact between the circulating fluid and the shaft, maintaining an operating limit of 125 PSI. A ceramic and EPT mechanical seal manages fluid containment within the pump assembly.
The 15 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and utilizes a 200-230V 3PH power supply with a DOE PEI rating of 0.48. 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.
