This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a bronze shaft sleeve mounted on a stainless steel shaft. The dry shaft construction isolates the shaft from the circulating fluid to prevent corrosion. A mechanical seal utilizes ceramic faces and EPT rubber components to manage fluid containment. This assembly maintains an operating pressure rating of 125 PSI.
A 50 HP premium efficiency TEFC motor operates at 3450 RPM and incorporates Aegis grounding, utilizing 380-460V / 3PH power input with a DOE PEI 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.
