This centrifugal end suction pump incorporates a cast iron casing with center-line discharge, a bronze impeller, and a bronze shaft sleeve on a stainless steel shaft. The unit utilizes a dry shaft design that prevents circulating fluid from contacting the shaft and maintains a pressure rating of 125 PSI. A mechanical seal comprising a ceramic seat and EPT rubber ensures fluid containment during operation. The assembly integrates a replaceable wear ring within the volute.
This unit operates with a 7.5 HP Premium Efficiency TEFC motor at 1750 RPM, Aegis Grounding, 200-230V, and 3PH power supply, achieving a DOE PEI rating 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
