This base-mounted end suction pump utilizes a class 30 cast iron casing and a bronze impeller to facilitate fluid transfer. The design incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve, maintaining a dry shaft arrangement that isolates the shaft from the circulating fluid. A mechanical seal containing a ceramic seat and EPT components manages fluid containment, supporting operations up to 125 PSI. Integrally cast mounting feet on the casing provide structural support, while the assembly includes pressure tappings on both the suction and discharge connections for monitoring system performance.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, powered by 380-460V / 3PH current, with a DOE PEI of 0.46. 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.
