This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. A bronze shaft sleeve protects the stainless steel shaft through a dry shaft mechanical design, supporting pressures up to 125 PSI with a wear ring. This assembly incorporates a mechanical seal with ceramic components and EPT rubber. The volute configuration provides center-line discharge for positive air venting, while the design allows for servicing without disturbing system piping.
Powered by a 50 HP premium efficiency TEFC motor operating at 1750 RPM, this system integrates Aegis grounding for 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 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.
