This base-mounted end suction pump utilizes a cast iron casing with a center-line discharge and a bronze impeller. The assembly integrates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. Mechanical sealing is managed by a ceramic seat with EPT rubber components. This construction supports a maximum pressure rating of 125 PSI without a wear ring.
The motor operates at 15 HP with premium efficiency, a TEFC enclosure, a speed of 3450 RPM, Aegis grounding, and a power supply of 200-230V 3PH, achieving a DOE PEI rating of 0.47. 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.
