This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft paired with a replaceable bronze shaft sleeve, while the dry shaft design maintains operation up to 125 PSI. A mechanical seal with a ceramic seat and EPT rubber components facilitates fluid management. The pump casing integrates center-line discharge for air venting and provides mounting feet for structural support.
Powered by a 5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, the pump accepts a 380-460V / 3PH power supply and holds a DOE PEI rating of 0.45. 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.
