This base-mounted end suction pump incorporates a class 30 cast iron casing with integrally cast mounting feet and center-line discharge for air venting. The unit utilizes a bronze impeller dynamically balanced to ANSI Grade G6.3 and a stainless steel shaft covered by a replaceable bronze shaft sleeve. Engineering specifications include a dry shaft design that prevents circulating fluid from contacting the shaft and a mechanical seal constructed with ceramic seat and EPT rubber. This assembly is rated for 125 PSI system pressure.
The pump operates with a 5 HP Premium Efficiency TEFC motor at 1750 RPM, equipped with Aegis grounding and a power supply of 200-230V / 3PH, resulting in 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.
