This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet and center-line discharge. It incorporates a bronze impeller dynamically balanced to ANSI Grade G6.3 and a stainless steel shaft. A replaceable bronze shaft sleeve provides protection for the dry shaft design, which prevents circulating fluid from contacting the shaft. This assembly employs a mechanical seal comprised of a ceramic seat half and EPT rubber, maintaining a pressure rating of 125 PSI without a wear ring.
This assembly integrates a 75 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis Grounding, utilizing a 380-460V / 3PH power supply, with 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.
