This end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a replaceable bronze shaft sleeve and a dry shaft design, which prevents the circulating fluid from contacting the shaft. The assembly provides a 125 PSI pressure rating and is constructed with a wear ring. A mechanical seal using ceramic and EPT materials manages fluid containment.
The 40 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding on a 380-460V / 3PH power supply, achieving 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 an Electro-Mech bypass and main disconnect and holds a NEMA 1 / IP 21 enclosure rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
