This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The pump incorporates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. It utilizes a mechanical seal comprised of ceramic and EPT materials. The assembly is rated for a maximum pressure of 125 PSI without a wear ring.
The 75 HP Premium Efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, powered by a 380-460V / 3PH supply 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.
