This end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. The assembly incorporates a dry shaft design that prevents circulating fluid from contacting the shaft, supporting a 125 PSI pressure rating. It is constructed with a mechanical seal utilizing a ceramic seat and EPT rubber components.
The 1.5 HP Premium Efficiency TEFC motor operates at 1750 RPM and includes Aegis Grounding on a 200-230V / 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
