This base-mounted end suction pump incorporates a cast iron casing with an integrally cast mounting foot and a stainless steel impeller. The design utilizes a dry shaft that prevents contact between the circulating fluid and the stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft, while the mechanical seal is constructed with a ceramic seat half and EPT rubber. This assembly supports a maximum system pressure of 125 PSI without the use of a wear ring.
The 15 HP premium efficiency TEFC motor operates at 3450 RPM, integrates Aegis grounding, and receives power from a 380-460V 3PH supply, resulting in a DOE PEI rating 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.
