This end suction pump utilizes a cast iron casing with a stainless steel impeller and a bronze shaft sleeve covering a stainless steel shaft. The dry shaft design prevents contact between the circulating fluid and the shaft, maintaining integrity at 125 PSI. It incorporates a ceramic and EPT mechanical seal to manage fluid containment during operation. The pump construction includes integrally cast mounting feet on the volute to facilitate alignment and support within the system.
This assembly utilizes a 15 HP Premium Efficiency TEFC motor operating at 3450 RPM with Aegis grounding on 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.
