This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. The assembly incorporates a bronze shaft sleeve to protect the internal components and utilizes a ceramic and EPT mechanical seal. Engineered for dry shaft operation, the pump maintains a 125 PSI rating without a wear ring. Pressure tappings are provided on both the suction and discharge connections to facilitate system monitoring, while the center-line discharge design allows for positive air venting.
This assembly utilizes a 100 HP premium efficiency TEFC motor operating at 1750 RPM, integrated with Aegis grounding and a 380-460V / 3PH power supply, resulting in 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
