This base-mounted end suction pump integrates a class 30 cast iron casing with integrally cast mounting feet and center-line discharge to assist with air venting. The internal hydraulic assembly comprises a dynamically balanced bronze impeller, a stainless steel shaft, and a replaceable bronze shaft sleeve. Engineered with a dry shaft design, the unit prevents contact between the shaft and circulating fluid, reaching a maximum pressure rating of 125 PSI. A ceramic mechanical seal with EPT rubber provides fluid containment, while the internal wear ring maintains operational integrity.
The 15 HP premium efficiency TEFC motor operates at 3450 RPM and utilizes Aegis grounding, drawing power from a 200-230V / 3PH electrical supply with a DOE PEI rating of 0.45. 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.
