This close-coupled end suction pump comprises a cast iron casing with an integrated bronze impeller and a bronze shaft sleeve. Engineered with a dry shaft design that prevents contact between the circulating fluid and the pump shaft, the unit utilizes a mechanical seal with a ceramic seat and EPT rubber. This assembly maintains performance at pressures up to 125 PSI and incorporates a wear ring. The construction allows for the installation of filter-equipped flush seal line taps to protect the internal components from non-condensable particles, while standard pressure tappings on suction and discharge connections allow for consistent system monitoring.
The motor utilizes a 7.5 HP premium efficiency TEFC enclosure operating at 3450 RPM with Aegis grounding and a 208V 3PH power supply, achieving a DOE PEI rating of 0.42. 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.
