This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft paired with a replaceable bronze shaft sleeve in a dry shaft design that prevents contact between the circulating fluid and the shaft. A ceramic mechanical seal with EPT rubber provides sealing, supporting operation up to 125 PSI when configured without a wear ring. The pump casing integrates center-line discharge for air venting and includes ports for gauge connections.
The system operates with a 7.5 HP premium efficiency TEFC motor at 1750 RPM, equipped with Aegis grounding for operation on a 200-230V / 3PH power supply, yielding 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.
