This base-mounted end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid movement. The internal construction integrates a dry shaft design, which prevents contact between the circulating fluid and the stainless steel shaft. A replaceable bronze shaft sleeve surrounds the shaft to assist with maintenance. The pump assembly incorporates a mechanical seal composed of a ceramic seat and EPT rubber, providing a pressure rating of 125 PSI.
The assembly utilizes a 25 HP premium efficiency TEFC motor operating at 3450 RPM. This motor integrates Aegis grounding and functions on 200-230V, 3PH power with a DOE PEI rating 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.
