This base-mounted end suction pump incorporates a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft. It utilizes a bronze shaft sleeve to isolate the shaft from circulating fluid in this dry shaft design, which sustains 125 PSI without a wear ring. The pump comprises a mechanical seal constructed with a ceramic seat and EPT rubber.
The assembly operates with a 7.5 HP Premium Efficiency TEFC motor at 1750 RPM with Aegis Grounding and a 200-230V / 3PH power supply, yielding a DOE PEI 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.
