This base-mounted end suction pump incorporates a cast iron casing with an integrally cast bronze impeller and a bronze shaft sleeve mounted over a stainless steel shaft. The assembly utilizes a dry shaft design that prevents contact between the circulating fluid and the shaft, which operates at a pressure rating of 125 PSI with an included wear ring. A mechanical seal utilizes a ceramic seat and EPT rubber to maintain system integrity.
Powered by a 7.5 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly incorporates Aegis grounding and accepts a 200-230V 3PH power supply, yielding a DOE PEI rating of 0.44. 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.
