This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft with a replaceable bronze shaft sleeve, employing a dry shaft design that prevents circulating fluid from contacting the shaft. Mechanical sealing consists of a ceramic seat paired with EPT rubber elements. The volute includes center-line discharge for air venting, and the unit maintains a 125 PSI pressure rating without a wear ring.
The motor operates at 30 HP with a Premium Efficiency rating in a TEFC enclosure at 1750 RPM, integrating Aegis grounding and a 380-460V / 3PH power supply, yielding a DOE PEI 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.
