This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The design incorporates a dry shaft that prevents circulating fluid from contacting the stainless steel shaft. A replaceable bronze shaft sleeve protects the assembly, while the mechanical seal utilizes a ceramic seat and EPT rubber. This pump unit maintains a pressure rating of 125 PSI.
Powered by a 75 HP premium efficiency TEFC motor, the pump operates at 3450 RPM and integrates Aegis grounding. The motor connects to a 380-460V / 3PH power supply, and the assembly carries 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.
