This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve, which prevents fluid contact with the shaft. It utilizes a mechanical seal constructed with a ceramic seat and EPT rubber. This assembly supports a pressure rating of 125 PSI without a wear ring.
The pump operates with a 1.5 HP premium efficiency TEFC motor at 1750 RPM, utilizing Aegis grounding for the 380-460V, 3PH power supply, and carries 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.
