This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft protected by a bronze shaft sleeve. Engineered with a dry shaft design, the assembly prevents contact between the circulating fluid and the pump shaft, supporting a 125 PSI pressure rating. The mechanical seal assembly consists of a ceramic seat half with EPT rubber elements to maintain system integrity. Flush seal line taps are integrated into the casing to facilitate the installation of a filter for protection against non-condensable particles in open systems.
The motor is a 5 HP Premium Efficiency TEFC unit operating at 1750 RPM with Aegis Grounding on a 380-460V / 3PH power supply, resulting in a DOE PEI of 0.44. 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.
