This close-coupled end suction pump incorporates a cast iron casing and cover combined with a stainless steel impeller and a bronze shaft sleeve. The dry shaft design prevents contact between the circulating fluid and the pump shaft, while the mechanical seal assembly utilizes a ceramic seat half and EPT rubber. This assembly supports a maximum pressure rating of 125 PSI and incorporates a wear ring to maintain hydraulic performance. Flush seal line taps are provided on the unit to enable filter installation for protection against non-condensable particles, and the casing connections include pressure tappings for suction and discharge monitoring.
Powered by a 40 HP premium efficiency TEFC motor, this assembly operates at 3450 RPM with Aegis shaft grounding on a 380-460V 3PH power supply. 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.
