This base-mounted end suction pump utilizes a cast iron casing with an integrally cast mounting base and a centerline discharge. The assembly incorporates a stainless steel NSF61 impeller keyed to a stainless steel shaft, which is protected by a dry shaft design and a bronze shaft sleeve. Sealing is accomplished via an EPT and ceramic mechanical seal rated for 125 PSI without a wear ring. The bearing housing contains permanently lubricated, sealed-for-life ball bearings engineered for long-term operational consistency.
Powered by a 1.5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding and a 200-230V / 3PH power supply, the unit integrates into industrial systems. 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.
