This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller coupled with a stainless steel shaft. It utilizes a dry shaft design that prevents circulating fluid from contacting the shaft, which is shielded by a replaceable bronze shaft sleeve. The mechanical seal consists of a ceramic seat with EPT rubber, providing a 125 PSI pressure rating without the use of a wear ring.
Operating with a 15 HP premium efficiency TEFC motor at 3450 RPM, the assembly integrates Aegis grounding on a 380-460V 3PH power supply with a DOE PEI rating of 0.47. 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.
