This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a stainless steel shaft. The assembly utilizes a dry shaft design that prevents circulating fluid from contacting the shaft and includes a bronze shaft sleeve to facilitate seal maintenance. A mechanical seal with a ceramic seat and EPT rubber provides leak protection, and the design accommodates an operating pressure of 125 PSI when configured without a wear ring.
Powered by a 30 HP Premium Efficiency TEFC motor, the system operates at 1750 RPM and incorporates Aegis grounding and 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
