This end suction pump incorporates a cast iron casing, a bronze impeller, and a bronze shaft sleeve fitted over a stainless steel shaft. The assembly utilizes a dry shaft design rated for 125 PSI and includes a wear ring. A mechanical seal constructed with a ceramic seat and EPT rubber components provides internal protection against leakage.
Powered by a 25 HP premium efficiency ODP motor operating at 1750 RPM, the assembly utilizes Aegis grounding and runs on 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
