This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a bronze impeller. The assembly utilizes a stainless steel shaft with a replaceable bronze shaft sleeve and a dry shaft design that prevents circulating fluid from contacting the shaft. The mechanical seal assembly incorporates a silicon-carbide seat half and EPT rubber components. This unit maintains a 125 PSI pressure rating and includes a wear ring.
Powered by a 20 HP Premium Efficiency TEFC motor at 1750 RPM with Aegis Grounding and a 200-230V / 3PH power supply, the assembly meets 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.
