This base-mounted end suction pump comprises a cast iron casing with an integrated bronze impeller and a stainless steel shaft. It incorporates a replaceable bronze shaft sleeve that protects the shaft from direct contact with circulating fluid in a dry shaft design. The mechanical seal assembly utilizes ceramic and EPT components, providing a pressure rating of 125 PSI. Gauging ports for suction and discharge connections allow for monitoring system conditions.
This pump utilizes a 20 HP premium efficiency TEFC motor operating at 1750 RPM, equipped with Aegis grounding and powered by 208V 3PH electricity, 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.
