This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller to facilitate fluid movement. The assembly utilizes a bronze shaft sleeve and a dry shaft design that prevents fluid contact with the pump shaft, while the mechanical seal is constructed with a ceramic seat and EPT rubber. Pressure tappings are provided on both the suction and discharge connections. This unit operates at a maximum pressure of 125 PSI without the use of a wear ring.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis grounding and a 380-460V, 3PH power supply, resulting in a DOE PEI rating of 0.46. The "S" in the SCI 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.
