This end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve. The dry shaft assembly prevents circulating fluid from contacting the shaft and operates at 125 PSI. An EPT rubber and ceramic seat mechanical seal manages fluid containment at the shaft interface. This pump construction supports maintenance without disturbing system piping and incorporates integrated mounting feet for secure installation.
The assembly utilizes a 50 HP premium efficiency TEFC motor operating at 1750 RPM, which integrates Aegis grounding and utilizes 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.
