This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It integrates a bronze shaft sleeve and a stainless steel shaft within a dry shaft design that prevents contact between the shaft and circulating fluid. The unit utilizes a mechanical seal comprised of a tungsten carbide seat and EPT rubber. Engineered for a maximum pressure of 125 PSI, the assembly incorporates a wear ring.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM, utilizes Aegis grounding, and accepts a 380-460V 3PH power supply with a DOE PEI rating of 0.45. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
