This base-mounted end suction pump comprises a cast iron casing with center-line discharge and an integrally cast bronze impeller. The design integrates a dry shaft construction that prevents the circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. A mechanical seal utilizes ceramic and EPT materials for operation at pressures up to 125 PSI. This configuration allows for servicing internal components without disturbing the system piping.
The assembly integrates a 3 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis grounding, powered by 200-230V 3PH electricity and maintaining 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
