This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The pump integrates a dry shaft design with a stainless steel shaft covered by a replaceable bronze shaft sleeve. A ceramic and EPT mechanical seal manages fluid containment. The unit is rated for a maximum operating pressure of 125 PSI.
The assembly is powered by a 40 HP premium efficiency TEFC motor operating at 3450 RPM, equipped with Aegis grounding for a 380-460V 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
