This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft paired with a replaceable bronze shaft sleeve and incorporates a dry shaft design that prevents contact between the circulating fluid and the shaft. A mechanical seal with a ceramic seat and EPT rubber provides fluid containment within the pump housing. These components facilitate serviceability while maintaining structural integrity during operation.
The 15 HP Premium Efficiency TEFC motor operates at 3450 RPM and integrates Aegis grounding for protection against electrical discharge, utilizing a 380-460V 3PH power supply with a DOE PEI rating of 0.45. 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.
