This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft paired with a replaceable bronze shaft sleeve. Engineered with a dry shaft design, the pump construction prevents contact between the circulating fluid and the shaft. A mechanical seal incorporating ceramic and EPT materials secures the unit, which provides a pressure rating of 125 PSI.
This assembly runs on a 50 HP Premium Efficiency TEFC motor at 1750 RPM, utilizing Aegis Grounding and a 380-460V / 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.
