This close-coupled end suction pump is constructed with a cast iron casing and a bronze impeller. The pump incorporates a dry shaft design that eliminates contact between the circulating fluid and the shaft, utilizing a bronze shaft sleeve to facilitate maintenance. The mechanical seal assembly consists of a ceramic seat and EPT rubber components. This configuration supports operation at pressures up to 125 PSI without a wear ring.
The 50 HP premium efficiency TEFC motor operates at 1750 RPM, integrates Aegis grounding, and functions on 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 an electro-mechanical bypass with main disconnect, 5kA SCCR, drive fusing, and a third contactor, holding an enclosure NEMA Type 3R / IP 64 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
