This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a bronze impeller. The assembly utilizes a stainless steel shaft with a replaceable bronze shaft sleeve, employing a dry shaft design that prevents circulating fluid from contacting the shaft. A ceramic and EPT mechanical seal regulates the system, supporting a maximum pressure rating of 125 PSI. The bearing frame incorporates permanently lubricated, sealed-for-life ball bearings to facilitate maintenance without disturbing system piping.
Powered by a 2 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly integrates Aegis shaft grounding, a 380-460V 3PH power supply, and 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.
