This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a center-line discharge for air venting. The unit integrates a bronze impeller and a bronze shaft sleeve over a stainless steel shaft, utilizing a dry shaft design that prevents circulating fluid from contacting the shaft. A mechanical seal with a ceramic seat and EPT rubber manages fluid containment at pressures reaching 125 PSI. This assembly incorporates a replaceable wear ring within the volute to maintain hydraulic performance standards.
Operating with a 30 HP Premium Efficiency TEFC motor at 1750 RPM, the pump integrates Aegis grounding and accepts 380-460V / 3PH power input with 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.
