This base-mounted end suction pump utilizes a cast iron casing and a bronze impeller. The pump integrates a dry shaft design to prevent circulating fluid from contacting the stainless steel shaft, which is covered by a replaceable bronze shaft sleeve. The mechanical seal consists of EPT rubber and a ceramic seat, maintaining a pressure rating of 125 PSI without a wear ring.
Powered by a 7.5 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly utilizes Aegis grounding and a 380-460V / 3PH power supply, achieving 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.
