This end suction pump is constructed with a cast iron casing and a bronze impeller, utilizing a dry shaft design that prevents contact between the shaft and circulating fluid. The assembly integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve and a ceramic-EPT mechanical seal. Designed for a 125 PSI working pressure, the unit incorporates a wear ring to provide hydraulic stability.
This unit utilizes a 3 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis grounding on a 200-230V / 3PH power supply, resulting in a DOE: PEI = 0.45 rating. 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.
