This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller to facilitate fluid transfer. The assembly utilizes a dry shaft construction with a stainless steel shaft and a replaceable bronze shaft sleeve, which serves to isolate the rotating components from the circulating fluid. Sealing for the pump comprises a mechanical seal with a ceramic seat and EPT rubber, providing a pressure rating of 125 PSI.
A 5 HP premium efficiency TEFC motor operating at 3450 RPM integrates Aegis grounding and utilizes a 380-460V / 3PH power supply, resulting in a DOE PEI rating of 0.47. 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.
