This base-mounted end suction pump incorporates a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft. A replaceable bronze shaft sleeve protects the internal components, and the assembly utilizes a mechanical seal constructed with a ceramic seat and EPT rubber. This dry shaft design permits operation at pressures up to 125 PSI without the use of a wear ring, while flush seal line taps allow for the integration of external filtration to manage particulates.
Powered by a 40 HP premium efficiency TEFC motor operating at 1750 RPM, the pump utilizes Aegis grounding and accepts a 380-460V / 3PH power supply, 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
