This close-coupled end suction pump comprises a cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design that prevents circulating fluid from contacting the pump shaft, supported by a replaceable bronze shaft sleeve. A mechanical seal with a ceramic seat and EPT rubber components maintains hydraulic integrity within the 125 PSI pressure limit. This pump construction incorporates flush seal line taps to allow for the integration of optional filtration systems.
The 20 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis grounding and utilizes a 380-460V / 3PH power supply, resulting in 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
