This base-mounted end suction pump comprises a cast iron casing with center-line discharge and an integrated bronze impeller. The mechanical design utilizes a dry shaft construction with a stainless steel shaft and a replaceable bronze shaft sleeve to isolate the shaft from circulating fluids. The assembly incorporates a silicon-carbide seat and EPT rubber mechanical seal, and the pump casing supports operating pressures up to 125 PSI with a wear ring.
Powered by a 30 HP premium efficiency ODP motor, the unit operates at 1750 RPM with Aegis grounding on a 380-460V 3PH power 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
