This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and center-line discharge for positive air venting. The unit incorporates a bronze impeller dynamically balanced to ANSI Grade G6.3 and a stainless steel shaft covered by a replaceable bronze shaft sleeve. Engineering this assembly with a dry shaft design isolates the shaft from the circulating fluid to limit corrosion risk. Mechanical sealing is managed by a ceramic seat and EPT rubber components, with the system rated for 125 PSI operation. A replaceable bronze wear ring integrates into the casing to maintain hydraulic efficiency during extended use.
The 5 HP Premium Efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, powered by a 380-460V 3PH electrical supply with a DOE PEI 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
