This base-mounted end suction pump utilizes a cast iron casing with a center-line discharge and integrally cast mounting feet. The rotating assembly incorporates a bronze impeller balanced to ANSI Grade G6.3 and a stainless steel shaft protected by a replaceable bronze shaft sleeve. This mechanical design utilizes a dry shaft configuration that isolates the shaft from the circulating fluid to limit exposure to potential corrosion. The assembly includes a ceramic seat and EPT rubber mechanical seal, and the pump maintains a pressure rating of 125 PSI.
Power is provided by a 20 HP premium efficiency TEFC motor operating at 3450 RPM, which integrates Aegis grounding and utilizes a 380-460V / 3PH power supply, resulting in 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.
