This base-mounted end suction pump utilizes a class 30 cast iron casing for positive air venting and center-line discharge. The construction integrates a dynamically balanced bronze impeller fitted to a stainless steel shaft. Protection of the shaft is achieved through a dry shaft design, which prevents contact with the circulating fluid, complemented by a replaceable bronze shaft sleeve. The mechanical seal assembly consists of a ceramic seat and EPT rubber, rated for a maximum pressure of 125 PSI.
Powered by a 15 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding, the electrical assembly supports 380-460V 3PH power with a DOE PEI rating of 0.43. 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.
