This centrifugal end suction pump incorporates a cast iron casing and a bronze impeller. The design utilizes a dry shaft configuration with a replaceable bronze shaft sleeve and a stainless steel shaft to prevent fluid contact. A mechanical seal assembly consists of ceramic and EPT materials, supporting operation at pressures up to 125 PSI without a wear ring. This pump comprises a single-stage unit with center-line discharge for air venting and provides integrally cast mounting feet.
Powered by a 5 HP premium efficiency TEFC motor operating at 3450 RPM, the assembly utilizes Aegis grounding on a 380-460V / 3PH power supply with 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.
