This centrifugal end suction pump integrates a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a dry shaft design that isolates the shaft from the circulating fluid, utilizing a replaceable bronze shaft sleeve to facilitate maintenance. The pump assembly employs a ceramic and EPT mechanical seal. Construction includes integrally cast mounting feet for structural support. This unit operates at a maximum pressure of 125 PSI.
The 75 HP Premium Efficiency TEFC motor operates at 1750 RPM, integrates Aegis Grounding, and functions on 380-460V / 3PH power, resulting in a DOE PEI rating of 0.46. 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.
