This base-mounted end suction pump incorporates a cast iron casing with a bronze impeller and a stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft from contact with circulating fluid in accordance with the dry shaft design. The mechanical seal utilizes a ceramic seat and EPT rubber components to maintain performance at system pressures reaching 125 PSI.
The 50 HP premium efficiency TEFC motor operates at 3450 RPM and integrates Aegis grounding with 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.
