This domestic water booster set incorporates a cast iron casing with a bronze impeller and a stainless steel shaft. It integrates a replaceable bronze shaft sleeve and a dry shaft mechanical design rated for 125 PSI without a wear ring. The assembly utilizes a ceramic seat half and EPT rubber components to provide a seal for the fluid path. The pump construction comprises center-line discharge and integrally cast mounting feet to facilitate air venting during operation.
This assembly utilizes a 40 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding, powered by 380-460V 3PH electrical input, yielding a DOE PEI of 0.48. 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.
