This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design that prevents the circulating fluid from contacting the stainless steel shaft, which is covered by a bronze shaft sleeve. A mechanical seal comprising a ceramic seat and EPT rubber manages fluid containment within the pump. This configuration maintains a pressure rating of 125 PSI without a wear ring.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, powered by a 380-460V 3PH supply, with 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
