This close-coupled end suction pump incorporates a cast iron casing with a bronze impeller and a bronze shaft sleeve. The dry shaft assembly eliminates contact between the shaft and the circulating fluid, while the internal mechanical seal utilizes a ceramic seat half and EPT rubber. This design maintains an operating pressure rating of 125 PSI without a wear ring. The pump includes flush seal line taps to facilitate filter installation and provides pressure tappings on both the suction and discharge connections for monitoring system performance.
The assembly utilizes a 5 HP premium efficiency TEFC motor operating at 1750 RPM with an Aegis grounding ring, powered by a 200-230V 3PH supply, achieving a DOE PEI rating of 0.43. 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.
