This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It integrates a bronze shaft sleeve on a stainless steel shaft within a dry shaft design that prevents fluid contact with the shaft, while also including a ceramic seat and EPT rubber mechanical seal. The assembly operates at a 125 PSI pressure rating and incorporates a replaceable wear ring for maintenance.
Powered by a 40 HP premium efficiency ODP motor at 1750 RPM, the pump utilizes Aegis grounding and operates on 380-460V / 3PH power, resulting in a DOE PEI 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.
