This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a dry shaft design that prevents contact between the circulating fluid and the shaft, which is protected by a bronze shaft sleeve. The mechanical seal assembly comprises an EPT rubber component and a ceramic seat half, allowing for operation at pressures up to 125 PSI. This construction facilitates field maintenance and component replacement without disturbing the system piping.
The motor utilizes a 100 HP Premium Efficiency TEFC design operating at 1750 RPM with Aegis Grounding, powered by a 380-460V / 3PH electrical supply, yielding 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
