This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a bronze shaft sleeve mounted on a stainless steel shaft. The assembly utilizes a dry shaft design that prevents circulating fluid from contacting the shaft and incorporates a ceramic and EPT mechanical seal. This unit sustains a pressure rating of 125 PSI and utilizes pressure tappings on the suction and discharge connections to facilitate system monitoring. The construction employs a center-line discharge configuration for air venting and includes a bearing housing with permanently lubricated sealed-for-life ball bearings.
The 7.5 HP premium efficiency TEFC motor operates at 3450 RPM, incorporates Aegis grounding, and accepts 380-460V / 3PH power, resulting in 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.
