This base-mounted end suction pump utilizes a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. The assembly incorporates a dry shaft design that prevents contact between the circulating fluid and the shaft, maintaining an operating pressure rating of 125 PSI without a wear ring. A ceramic and EPT mechanical seal provides fluid containment within the housing. The design allows for system maintenance without disrupting piping connections, while pressure tappings on the suction and discharge points allow for standardized gauge monitoring.
The pump assembly utilizes a 30 HP premium efficiency ODP motor operating at 1750 RPM, integrated with Aegis grounding and powered by a 380-460V 3PH supply, resulting in a DOE PEI rating 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
