This base-mounted end suction pump utilizes a cast iron casing with an integral center-line discharge and bronze impeller. The design incorporates a dry shaft construction that prevents fluid contact with the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. A ceramic and EPT mechanical seal facilitates fluid containment and supports a pressure rating of 125 PSI without a wear ring. The bearing housing encompasses sealed-for-life ball bearings to support the rotating assembly.
The motor operates at 30 HP with Premium Efficiency, TEFC enclosure, 3450 RPM, Aegis Grounding, and 200-230V / 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
