This base-mounted end suction pump comprises a class 30 cast iron casing with a center-line discharge and a bronze impeller. The unit integrates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft. A replaceable bronze shaft sleeve covers the shaft, while the mechanical seal utilizes a ceramic seat and EPT rubber. The assembly is rated for 125 PSI operation without a wear ring and provides pressure tappings on both the suction and discharge connections for monitoring system performance.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, powered by a 380-460V / 3PH supply with a DOE PEI rating 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.
