This base-mounted end suction pump comprises a cast iron casing with an integrally cast mounting foot and a bronze impeller. The assembly utilizes a dry shaft design, which prevents the circulating fluid from contacting the stainless steel shaft. A bronze shaft sleeve covers the shaft to protect against wear. The unit incorporates a mechanical seal assembly with a ceramic seat and EPT rubber, providing a 125 PSI operating pressure rating.
The 5 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, powered by a 380-460V / 3PH supply with a DOE PEI of 0.45. 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.
