This base-mounted end suction pump utilizes a class 30 cast iron casing and a bronze impeller to move fluid within a system. The assembly integrates a stainless steel shaft covered by a bronze shaft sleeve, which maintains a dry shaft design that prevents the circulating fluid from contacting the shaft. A ceramic and EPT mechanical seal secures the pump, which maintains a 125 PSI pressure rating and includes a wear ring to support consistent hydraulic performance.
The 50 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis grounding on a 380-460V / 3PH power supply, achieving 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.
