This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a bronze shaft sleeve on a stainless steel shaft. The assembly utilizes a dry shaft design that prevents the circulating fluid from contacting the pump shaft. Mechanical sealing is provided by a silicon-carbide seat half and EPT rubber components, maintaining pressure ratings up to 125 PSI. This pump incorporates an integrally cast mounting foot to provide structural stability during operation.
Powered by a 5 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis Grounding, this pump utilizes 380-460V / 3PH power and 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.
