This base-mounted end suction pump comprises a cast iron casing with a center-line discharge and a bronze impeller. The assembly integrates a stainless steel shaft with a replaceable bronze shaft sleeve, utilizing a dry shaft design that prevents contact between the circulating fluid and the shaft. A mechanical seal with a ceramic seat and EPT rubber components provides fluid containment, while the construction remains rated for 125 PSI operation. Pressure tappings on the suction and discharge connections allow for monitoring, and the volute includes integrally cast mounting feet.
Powered by a 5 HP premium efficiency TEFC motor operating at 3450 RPM, the assembly integrates Aegis shaft grounding and operates on 380-460V / 3PH power, achieving a DOE PEI of 0.47. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
