This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design incorporates a bronze shaft sleeve over a stainless steel shaft in a dry shaft configuration to prevent fluid contact. A ceramic and EPT mechanical seal supports system pressures up to 125 PSI. The casing integrates gauge ports at the suction and discharge connections to monitor performance, allowing for maintenance without disturbing system piping.
The assembly utilizes a 7.5 HP premium efficiency TEFC motor at 1750 RPM, which integrates Aegis grounding, a 380-460V / 3PH power supply, and carries a DOE PEI of 0.48. 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.
