This base-mounted end suction pump comprises a class 30 cast iron casing and a bronze impeller. The assembly integrates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft. A bronze shaft sleeve protects the shaft while facilitating maintenance, and the mechanical seal utilizes a ceramic seat with EPT rubber components. Designed for a 125 PSI pressure limit without a wear ring, the pump housing incorporates tapped gauge ports at the suction and discharge connections to simplify system monitoring.
Powered by a 125 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly integrates Aegis grounding and utilizes a 380-460V / 3PH power supply. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
