This base-mounted end suction pump utilizes a class 30 cast iron casing with center-line discharge and integrally cast mounting feet. The assembly incorporates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. A mechanical dry shaft design maintains isolation between the shaft and circulating fluid. The seal assembly comprises a ceramic seat and EPT rubber, providing a rated pressure of 125 PSI without the use of a wear ring.
The pump operates with a 5 HP Premium Efficiency TEFC motor at 3450 RPM, which integrates Aegis grounding and utilizes 380-460V 3PH power, resulting in a DOE PEI rating of 0.49. 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.
