This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft covered by a bronze shaft sleeve, which prevents contact between the circulating fluid and the shaft. A ceramic seat and EPT rubber mechanical seal comprise the shaft sealing arrangement. This dry shaft configuration maintains a pressure rating of 125 PSI without a wear ring.
The 15 HP, premium efficiency, ODP motor operates at 1750 RPM, integrates Aegis grounding, and receives power via 380-460V / 3PH, maintaining a DOE PEI 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
