This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly integrates a dry shaft design that prevents fluid contact with the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. This pump utilizes a ceramic mechanical seal with EPT rubber and is rated for 125 PSI. A replaceable bronze wear ring is located within the volute. The construction allows for service without disturbing the piping connections.
The pump operates with a 7.5 HP premium efficiency TEFC motor at 1750 RPM, which integrates Aegis grounding and functions on 200-230V, 3PH power with a DOE PEI 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
