This domestic water booster set utilizes a cast iron casing with a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. The dry shaft design isolates the shaft from the circulating fluid and supports operating pressures up to 125 PSI. A mechanical seal with a ceramic seat and EPT rubber gaskets manages fluid containment within the pump assembly. The construction provides for center-line discharge and allows for system maintenance without disturbing the connected piping.
This assembly utilizes a 5 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis Grounding, powered by 380-460V 3PH input, resulting in a DOE PEI of 0.44. 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.
