This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a bronze shaft sleeve and a dry shaft design that prevents the circulating fluid from contacting the shaft. The mechanical seal assembly utilizes a ceramic seat half and EPT rubber, providing a pressure rating of 125 PSI without the use of a wear ring.
The motor is a 75 HP Premium Efficiency TEFC motor operating at 1750 RPM, which includes Aegis grounding and utilizes a 380-460V, 3PH power supply. 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.
