This base-mounted end suction pump incorporates a cast iron casing with integrally cast mounting feet, paired with a bronze impeller and a bronze shaft sleeve over a stainless steel shaft. The assembly utilizes a dry shaft design that prevents fluid contact with the rotating shaft, and includes a wear ring rated for 125 PSI operation. A mechanical seal maintains containment, utilizing a ceramic seat and EPT rubber components to ensure system integrity.
The pump utilizes a 3 HP Premium Efficiency TEFC motor operating at 1750 RPM, equipped with Aegis Grounding and configured for 380-460V / 3PH power supply, resulting in a DOE PEI of 0.47. 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.
