This base-mounted end suction pump incorporates a cast iron casing with a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. The dry shaft design prevents fluid contact with the pump shaft, operating at a maximum pressure of 125 PSI without a wear ring. The assembly integrates a mechanical seal constructed with a ceramic seat and EPT rubber.
Driven by a 30 HP premium efficiency TEFC motor operating at 3450 RPM, the assembly integrates Aegis shaft grounding and accepts a 380-460V 3PH power supply, resulting in a DOE PEI rating of 0.48. 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.
