This base-mounted end suction pump incorporates a cast iron casing and a stainless steel impeller, engineered for a 125 PSI maximum operating pressure. The unit utilizes a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. This assembly integrates a ceramic and EPT mechanical seal rated for temperatures up to 250 °F.
Powered by a 5 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis grounding, this system accepts a 380-460V / 3PH power supply and maintains a DOE PEI rating of 0.44. 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.
