This base-mounted end suction pump comprises a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft. It incorporates a bronze shaft sleeve to facilitate seal maintenance and utilizes a dry shaft design that prevents circulating fluid from contacting the shaft. The mechanical seal assembly consists of a ceramic seat half and EPT rubber, supporting operation up to 125 PSI.
Powered by a 7.5 HP premium efficiency ODP motor, this assembly operates at 1750 RPM, incorporates Aegis grounding, and receives power via 200-230V / 3PH. The unit maintains a DOE PEI rating of 0.44. 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.
