This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller to manage fluid transfer. The assembly utilizes a dry shaft design that eliminates contact between the shaft and circulating fluid, while the bronze shaft sleeve provides protection. A mechanical seal constructed with a ceramic seat and EPT rubber components maintains system integrity at a maximum pressure of 125 PSI. Flush seal line taps are integrated into the pump, allowing for the installation of external filters to protect against non-condensable particles. The housing provides pressure tappings on both the suction and discharge connections to facilitate system monitoring.
The assembly utilizes a 7.5 HP premium efficiency TEFC motor that operates at 1750 RPM, incorporates Aegis grounding, and accepts 380-460V / 3PH power input, with a DOE PEI rating 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.
