This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft paired with a replaceable bronze shaft sleeve, facilitating a dry shaft design that isolates the shaft from the circulating fluid. The mechanical seal incorporates a ceramic seat half with EPT rubber elements, rated for 125 PSI.
Powered by a 5 HP premium efficiency TEFC motor, the assembly operates at 1750 RPM and incorporates Aegis grounding, 200-230V, 3PH power supply, and a DOE PEI rating of 0.48. 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.
