This base-mounted end suction pump is constructed with a cast iron casing incorporating center-line discharge and integral mounting feet. The assembly utilizes a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. Engineered with a dry shaft design, the mechanical seal utilizes a ceramic seat with EPT rubber to handle internal pressures up to 125 PSI without a wear ring. This configuration prevents contact between the circulating fluid and the pump shaft, ensuring consistent operation while maintaining structural integrity.
The assembly utilizes a 25 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding, configured for a 380-460V / 3PH power supply with a DOE PEI rating of 0.45. 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.
