This centrifugal end suction pump integrates a cast iron casing with a bronze impeller and a stainless steel shaft protected by a bronze shaft sleeve. The dry shaft design prevents circulating fluid from contacting the shaft, while a mechanical seal with an EPT rubber component and a ceramic seat manages internal fluid containment. This pump maintains a pressure rating of 125 PSI without a wear ring.
The 7.5 HP Premium Efficiency TEFC motor operates at 3450 RPM with Aegis Grounding on a 380-460V 3PH power supply, resulting in a DOE PEI of 0.45. 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.
