This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. The design integrates a stainless steel shaft paired with a replaceable bronze shaft sleeve, utilizing a dry shaft construction to prevent contact between the circulating fluid and the shaft. A ceramic mechanical seal with EPT rubber provides sealing functionality at a 125 PSI pressure rating.
The assembly utilizes a 25 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding on a 200-230V / 3PH power supply, yielding 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.
