This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design, integrating a stainless steel shaft covered by a bronze shaft sleeve to prevent fluid contact. Mechanical sealing is achieved with a silicon-carbide seat and EPT rubber components. This unit supports system operation up to 125 PSI without a wear ring and includes gauge ports at the suction and discharge connections to facilitate system monitoring.
Powered by a 25 HP Premium Efficiency ODP motor operating at 1750 RPM with Aegis Grounding, the assembly runs on 380-460V / 3PH power and maintains 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.
