This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft paired with a bronze shaft sleeve to maintain the dry shaft design, which provides operation at 125 PSI. Mechanical sealing is managed through a ceramic seat and EPT rubber component. Pressure tappings are integrated into both the suction and discharge connections to facilitate system monitoring.
The 15 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis grounding and utilizes a 380-460V / 3PH power supply, resulting in a DOE PEI 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.
