This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a bronze shaft sleeve as part of a dry shaft design, which prevents the circulating fluid from contacting the shaft and supports an operating pressure of 125 PSI. The mechanical seal assembly comprises an EPT rubber component with a ceramic seat.
Powered by a 5 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly integrates Aegis grounding and utilizes a 380-460V / 3PH power supply with a DOE PEI rating of 0.44. 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 utilizes a Delta-P HVAC drive set for lead/lag control in one zone, 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.
