This base-mounted end suction pump utilizes a cast iron casing with a center-line discharge for air venting. The unit integrates a bronze impeller and a stainless steel shaft, protected by a dry shaft design to prevent fluid contact with the shaft itself. A replaceable bronze shaft sleeve assists with mechanical seal maintenance. The assembly comprises a ceramic seal with EPT rubber components, and the casing supports a 125 PSI operating pressure with an included wear ring.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, power delivery of 380-460V / 3PH, and 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.
