This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a bronze impeller. The design integrates a dry shaft with a replaceable bronze shaft sleeve and a stainless steel shaft to prevent fluid contact. This assembly utilizes a ceramic and EPT mechanical seal. The unit operates at a maximum pressure of 125 PSI.
The system utilizes a 3 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis shaft grounding, powered by 380-460V 3PH supply, resulting in a DOE PEI rating of 0.45. 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.
