This end suction pump is constructed with a cast iron casing and a bronze impeller to facilitate fluid movement. The assembly incorporates a stainless steel shaft with a replaceable bronze shaft sleeve and a dry shaft design that prevents contact between the circulating fluid and the shaft. A ceramic seat and EPT rubber mechanical seal maintain system integrity under pressures up to 125 PSI.
The 7.5 HP premium efficiency TEFC motor operates at 1750 RPM, integrates Aegis shaft grounding, and functions on 200-230V 3PH power with a DOE PEI rating 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
