This centrifugal end suction pump incorporates a cast iron casing with an integrated wear ring and a 125 PSI pressure rating. The assembly utilizes a bronze impeller and a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft, while the mechanical seal comprises a ceramic seat and EPT rubber components.
Powered by a 40 HP Premium Efficiency TEFC motor, this assembly operates at 1750 RPM and incorporates Aegis grounding on a 380-460V / 3PH power supply with 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-mechanical bypass with a main disconnect and 5kA SCCR and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
