This base-mounted end suction pump comprises a class 30 cast iron casing with center-line discharge and a bronze impeller. It incorporates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is covered by a replaceable bronze shaft sleeve. The assembly utilizes a mechanical seal constructed of ceramic and EPT components rated for 125 PSI. This configuration allows for servicing without the need to disturb existing system piping.
The 20 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, powered by 380-460V 3PH input, achieving a DOE PEI rating 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.
