This base-mounted end suction pump utilizes a cast iron casing with a center-line discharge and a bronze impeller. The assembly incorporates a dry shaft design with a stainless steel shaft and a replaceable bronze shaft sleeve to isolate the rotating components from circulating fluid. A mechanical seal with a ceramic seat and EPT rubber gaskets completes the sealing system, which supports operation at 125 PSI.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis grounding and utilizes a 200-230V / 3PH power supply, with a DOE: PEI of 0.44. 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.
