This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet. The assembly incorporates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve in a dry shaft configuration that eliminates fluid contact with the shaft. A mechanical seal constructed with a ceramic seat and EPT rubber components provides fluid containment, maintaining operational integrity at pressures up to 125 PSI. This design facilitates pump maintenance without disturbing connected system piping.
The 3 HP premium efficiency PMAC motor utilizes a TEFC enclosure and operates at 1750 RPM with Aegis grounding protection at 200-230V 3PH power supply, achieving a DOE PEI 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.
