This base-mounted end suction pump comprises a cast iron casing with a 125 PSI pressure rating and an integrated bronze wear ring. The rotating assembly utilizes a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve. Engineering this unit with a dry shaft design isolates the shaft from the circulating fluid to prevent corrosion. A mechanical seal with a ceramic seat and EPT rubber components maintains hydraulic integrity within the volute.
The 30 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and accepts 200-230V, 3PH power, achieving a DOE PEI rating 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.
