This base-mounted end suction pump incorporates a class 30 cast iron casing with an integral bronze impeller. The design utilizes a dry shaft construction that isolates the stainless steel shaft from the circulating fluid, while a replaceable bronze shaft sleeve assists in maintenance. The pump integrates a mechanical seal with a ceramic seat and EPT elastomers, engineered for a maximum pressure rating of 125 PSI.
The 20 HP Premium Efficiency TEFC motor operates at 1750 RPM, utilizes Aegis grounding for the 200-230V, 3PH power supply, and carries 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.
