This base-mounted end suction pump comprises a class 30 cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design with a stainless steel shaft protected by a replaceable bronze shaft sleeve. For fluid containment, it integrates a mechanical seal constructed with silicon-carbide seat halves and EPT rubber, providing a pressure rating of 125 PSI.
The pump operates with a 3 HP premium efficiency TEFC motor at 1750 RPM. This motor incorporates Aegis grounding and functions on 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.
