This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a bronze shaft sleeve surrounding a stainless steel shaft. The dry shaft assembly utilizes a mechanical seal constructed with ceramic seat halves and EPT rubber, maintaining a pressure rating of 125 PSI without a wear ring. This configuration allows for maintenance of the seal and bearing housing without disturbing system piping connections.
Powered by a 30 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly integrates Aegis grounding on a 380-460V / 3PH power supply with a DOE PEI rating of 0.46. 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.
