This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. It incorporates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft, while the mechanical seal is comprised of ceramic seat and EPT rubber components. This assembly maintains a rating of 125 PSI without the use of a wear ring.
The 10 HP premium efficiency TEFC motor operates at 1750 RPM and includes Aegis grounding with a 380-460V / 3PH power supply, yielding a DOE PEI 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 and fused disconnect and holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
