This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It incorporates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a bronze shaft sleeve. The assembly integrates a ceramic and EPT mechanical seal to maintain fluid integrity under operating pressures up to 125 PSI.
The 125 HP Premium Efficiency TEFC motor operates at 1750 RPM with Aegis grounding and utilizes 575-600V 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.
