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 construction that prevents the circulating fluid from contacting the stainless steel shaft. A bronze shaft sleeve protects the shaft while a mechanical seal with a ceramic seat and EPT components manages fluid retention. This unit operates at a maximum pressure of 125 PSI without a wear ring.
The assembly utilizes a 30 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, compatible with 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.
