This base-mounted end suction pump comprises a cast iron casing with center-line discharge and an integrally cast mounting foot for system support. The assembly incorporates a stainless steel impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve, which prevents contact between the shaft and the circulating fluid. A dry shaft mechanical seal design utilizes a ceramic seat and EPT rubber, providing a 125 PSI pressure rating without a wear ring. Pressure tappings exist on both suction and discharge connections for system monitoring.
This unit operates with a 7.5 HP premium efficiency TEFC motor at 1750 RPM, integrating Aegis shaft grounding to handle 200-230V, 3PH power with a DOE PEI rating of 0.45. 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.
