This close-coupled end suction pump comprises a cast iron casing and a bronze impeller. The assembly utilizes a bronze shaft sleeve and a dry shaft design to eliminate contact between the circulating fluid and the pump shaft. A mechanical seal, constructed with a ceramic seat half and EPT rubber, isolates the internal components. This unit operates up to 125 PSI and incorporates pressure tappings on the suction and discharge connections for system monitoring.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding for 380-460V 3PH power, with a DOE PEI 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.
