This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The design integrates a stainless steel shaft paired with a replaceable bronze shaft sleeve and a dry shaft configuration rated for 125 PSI with a wear ring. This pump utilizes a mechanical seal comprised of tungsten carbide and EPT components for fluid management.
Powered by a 50 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding, the assembly connects to a 380-460V / 3PH power supply. 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 mechanical disconnect without bypass and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
