This close-coupled end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly utilizes a bronze shaft sleeve and is engineered with the Taco mechanical dry shaft design, which protects the pump shaft from contact with the circulating fluid. The mechanical seal assembly comprises a ceramic seat half and EPT rubber components. This pump maintains a pressure rating of 125 PSI without a wear ring.
Operating with a 20 HP, premium efficiency, TEFC motor at 3450 RPM, this unit incorporates Aegis grounding and utilizes a 380-460V / 3PH power supply with a DOE PEI rating of 0.46. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
