This base-mounted end suction pump comprises a cast iron casing with a 125 PSI pressure rating and an integrally cast mounting foot. The assembly utilizes a bronze impeller and a stainless steel shaft, protected by a replaceable bronze shaft sleeve that prevents fluid contact via a dry shaft design. Mechanical sealing is maintained with a ceramic seat half and EPT rubber components, while the construction includes an internal wear ring to support consistent hydraulic operation.
Powered by a 5 HP premium efficiency ODP motor operating at 1750 RPM, this assembly incorporates Aegis grounding and operates on 380-460V / 3PH power with 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.
