This base-mounted end suction pump consists of a cast iron casing with a center-line discharge and a bronze impeller. The assembly incorporates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. Mechanical sealing is maintained through a ceramic and EPT seal assembly. The casing is rated for 125 PSI and integrates a wear ring for operational efficiency.
Powered by a 5 HP premium efficiency TEFC PMAC motor operating at 1750 RPM with Aegis grounding, the pump utilizes 380-460V / 3PH power and maintains a DOE PEI rating of 0.44. 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.
