This base-mounted end suction pump utilizes a cast iron casing with a 125 PSI pressure rating and incorporates a bronze impeller along with a stainless steel shaft. A replaceable bronze shaft sleeve covers the shaft, facilitating a dry shaft design that prevents the circulating fluid from contacting the internal rotating components. The mechanical seal consists of a ceramic seat and EPT rubber. Integral gauge ports on both the suction and discharge connections allow for pressure monitoring during operation.
The 5 HP premium efficiency ODP motor operates at 1750 RPM and integrates Aegis grounding with a 380-460V 3PH power supply, resulting in a DOE PEI of 0.45. 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.
