This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The design utilizes a stainless steel shaft covered by a replaceable bronze shaft sleeve, which facilitates maintenance through a dry shaft mechanical configuration. This assembly maintains a 125 PSI pressure rating and incorporates a mechanical seal composed of ceramic and EPT materials.
The pump utilizes a 7.5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding and a 200-230V/3PH power supply, yielding 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
