This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller. The dry shaft design uses a stainless steel shaft sleeve to isolate the pump shaft from the circulating fluid. A mechanical seal assembly utilizes a silicon-carbide seat half and EPT rubber. With a pressure rating of 125 PSI, the pump includes flush seal line taps to permit filter installation and integrated pressure tappings on the suction and discharge connections.
The 40 HP premium efficiency TEFC motor operates at 1750 RPM and includes Aegis grounding, powered by a 380-460V 3PH supply with a DOE PEI 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.
