This base-mounted end suction pump utilizes a class 30 cast iron casing with an integrally cast bronze impeller and a stainless steel shaft. The assembly incorporates a bronze shaft sleeve to protect the shaft and a mechanical seal constructed with a ceramic seat half and EPT rubber. This dry shaft design eliminates contact between the circulating fluid and the shaft, supporting a pressure rating of 125 PSI without the use of a wear ring.
Powered by a 1.5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, the unit operates on 200-230V / 3PH power and holds a DOE PEI rating of 0.52. 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.
