This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly incorporates a dry shaft design with a stainless steel shaft and a replaceable bronze shaft sleeve to prevent fluid contact with the rotating shaft. A ceramic and EPT mechanical seal operates within this dry shaft configuration, supporting a maximum pressure rating of 125 PSI. This unit includes gauge ports at both the suction and discharge connections to facilitate system monitoring during operation.
This assembly operates with a 40 HP premium efficiency TEFC motor at 1750 RPM, utilizing an Aegis grounding ring and a 200-230V 3PH power supply, resulting in 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
