This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly incorporates a stainless steel shaft paired with a bronze shaft sleeve to facilitate a dry shaft design, which prevents contact between the circulating fluid and the shaft. A mechanical seal constructed with a ceramic seat and EPT rubber components manages fluid containment at the pump shaft. This configuration supports a maximum pressure rating of 125 PSI without a wear ring.
Powered by a 25 HP premium efficiency ODP motor, the pump operates at 1750 RPM with Aegis shaft grounding and 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.
