This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly integrates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which utilizes a bronze shaft sleeve. A mechanical seal with a ceramic seat half and EPT rubber components maintains pressure containment. This pump supports a maximum pressure rating of 125 PSI and incorporates a wear ring within the casing construction.
Powered by a 25 HP Premium Efficiency TEFC motor, the assembly operates at 1750 RPM and includes Aegis Grounding on 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
