This base-mounted end suction pump comprises a class 30 cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design with a stainless steel shaft covered by a replaceable bronze shaft sleeve to isolate the shaft from circulating fluid. A mechanical seal with a ceramic seat and EPT rubber maintains a pressure rating of 125 PSI. The pump incorporates a wear ring within the casing to support hydraulic performance.
Powered by a 20 HP premium efficiency ODP motor operating at 1750 RPM, the assembly integrates Aegis grounding and runs on a 200-230V, 3PH power supply with 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
