This close-coupled end suction pump utilizes a cast iron casing with a bronze impeller and a bronze shaft sleeve. The dry shaft design eliminates contact between the circulating fluid and the shaft, which supports the mechanical seal, constructed with a ceramic seat and EPT rubber. This assembly operates at a maximum pressure of 125 PSI and incorporates flush seal line taps to allow filter installation for protection against non-condensable particles. Integrated pressure tappings facilitate monitoring at both the suction and discharge connections.
The assembly utilizes a 2 HP premium efficiency TEFC motor operating at 1750 RPM, which integrates Aegis grounding and connects to a 380-460V, 3PH power supply, resulting in a DOE PEI rating of 0.47. 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.
