This base-mounted end suction pump incorporates a cast iron casing with a bronze impeller and a bronze shaft sleeve on a stainless steel shaft. It utilizes a ceramic and EPT mechanical seal within a dry shaft design that accommodates pressures up to 125 PSI without a wear ring. This assembly allows for maintenance of the seal and bearing housing while the system piping remains intact. The pump construction includes integrally cast mounting feet on the casing to facilitate installation and structural support.
Powered by a 7.5 HP premium efficiency TEFC motor operating at 3450 RPM, the assembly utilizes Aegis grounding and accepts 380-460V 3PH power input, achieving a DOE PEI rating of 0.49. 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.
