This centrifugal end suction pump utilizes a cast iron casing and a bronze impeller to facilitate hydraulic performance. The unit incorporates a bronze shaft sleeve and a stainless steel shaft within a dry shaft design, which isolates the shaft from the circulating fluid for a pressure rating of 125 PSI. Sealing occurs through a mechanical seal comprised of a ceramic seat and EPT rubber components. This assembly enables maintenance of the pump without disturbing the system piping, while gauge ports allow for monitoring at the suction and discharge connections.
Power originates from a 5 HP Premium Efficiency TEFC motor operating at 1750 RPM, which integrates Aegis grounding and functions on 208V / 3PH power, achieving a DOE PEI of 0.44. 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.
