This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a stainless steel shaft. It utilizes a bronze shaft sleeve with a dry shaft design that prevents circulating fluid from contacting the shaft. The mechanical seal incorporates a ceramic seat and EPT rubber. This assembly sustains 125 PSI operation without a wear ring. The construction allows for servicing without disturbing system piping and provides pressure tappings on suction and discharge connections.
Powered by a 125 HP premium efficiency TEFC motor at 1750 RPM with Aegis grounding for 380-460V / 3PH power, the unit maintains 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.
