This base-mounted end suction pump incorporates a class 30 cast iron casing and a bronze impeller to facilitate hydraulic performance. The assembly utilizes a dry shaft design with a stainless steel shaft and replaceable bronze shaft sleeve, which prevents fluid contact with the shaft components. It integrates a mechanical seal constructed with ceramic seat halves and EPT rubber, maintaining a pressure rating of 125 PSI. This configuration permits service access to the seal and bearing housing without the removal of system piping.
The 20 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, powered by a 380-460V 3PH supply with 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.
