This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller. The design utilizes a dry shaft construction to isolate the stainless steel shaft from the circulating fluid, complemented by a replaceable bronze shaft sleeve. For pressure containment and sealing, the assembly utilizes a silicon-carbide mechanical seal with EPT rubber, rated for a maximum pressure of 125 PSI with an integrated wear ring. This configuration facilitates consistent fluid handling in hydronic systems.
Operating with 7.5 HP, the premium efficiency TEFC motor runs at 1750 RPM and incorporates Aegis grounding, 380-460V 3PH power supply, and a DOE PEI rating of 0.44. 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
