This base-mounted end suction pump utilizes a class 30 cast iron casing with a center-line discharge for air venting. The unit incorporates a bronze impeller and a bronze shaft sleeve assembled over a stainless steel shaft. A dry shaft design prevents circulating fluid from contacting the shaft, while the mechanical seal consists of a ceramic seat and EPT rubber. This assembly rests on a structural steel base with an integral drain pan, allowing for serviceability without disturbing the connected system piping.
The 7.5 HP Premium Efficiency TEFC motor operates at 3450 RPM with Aegis Grounding for a 200-240V 1PH power supply and has a DOE PEI of 0.49. 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.
