This close-coupled end suction pump comprises a cast iron casing housing a bronze impeller and a bronze shaft sleeve. The dry shaft design prevents contact between the shaft and the circulating fluid, while the mechanical seal utilizes a ceramic seat half and EPT rubber. This assembly supports operation at 125 PSI without the need for a wear ring.
The 25 HP premium efficiency TEFC motor operates at 3450 RPM, incorporates Aegis grounding, utilizes a 380-460V 3PH power supply, and carries a DOE PEI of 0.45. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
