This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The pump incorporates a stainless steel shaft paired with a bronze shaft sleeve. This assembly utilizes a dry shaft design that prevents the circulating fluid from contacting the shaft. The mechanical seal assembly consists of an EPT rubber component and a ceramic seat. Rated for 125 PSI operation without a wear ring, this pump is constructed to facilitate maintenance of the seal and bearings without disturbing the system piping.
Powered by a 3 HP Premium Efficiency TEFC motor operating at 3450 RPM, the system integrates Aegis grounding and a 200-230V 3PH power supply, resulting in a DOE PEI of 0.49. 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.
