This end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a dry shaft design that prevents the circulating fluid from contacting the shaft, which is protected by a replaceable bronze shaft sleeve. The mechanical seal assembly consists of a ceramic seat with EPT rubber elements, providing a mechanical seal rated for 125 PSI operation in configurations without a wear ring.
The 3 HP Premium Efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding on a 200-230V, 3PH power supply with a DOE PEI rating of 0.45. 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.
