This base-mounted end suction pump utilizes a cast iron casing with an integrally cast center-line discharge. The hydraulic assembly incorporates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. This dry shaft design prevents circulating fluid from contacting the shaft, supporting an operating pressure rating of 125 PSI without a wear ring. A mechanical seal consisting of ceramic and EPT materials manages fluid containment.
The 20 HP premium efficiency motor with an ODP enclosure operates at 3450 RPM and integrates Aegis grounding on a 200-230V 3PH power supply with a DOE PEI rating of 0.48. 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
