This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a stainless steel shaft. A bronze shaft sleeve covers the shaft, while the dry shaft design ensures the circulating fluid does not contact the shaft assembly at pressures up to 125 PSI. The unit integrates a mechanical seal constructed with a ceramic seat half and EPT rubber.
The assembly utilizes a 7.5 HP Premium Efficiency TEFC motor operating at 3450 RPM with Aegis grounding and a 380-460V / 3PH power supply, achieving 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.
