This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly utilizes a dry shaft design, which incorporates a stainless steel shaft protected by a replaceable bronze shaft sleeve to eliminate fluid contact. Hydraulic sealing is provided by a mechanical seal constructed with a ceramic seat and EPT rubber, rated for operation at pressures up to 125 PSI.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, accepting a 380-460V 3PH power supply, with a DOE PEI 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
