This end suction pump utilizes a center-line discharge cast iron casing and a bronze impeller. A dry shaft design protects the stainless steel shaft from circulating fluid contact by incorporating a replaceable bronze shaft sleeve. The pump assembly utilizes a mechanical seal comprised of a ceramic seat and EPT rubber. This configuration maintains a pressure rating of 125 PSI without a wear ring. The bearing housing integrates permanently lubricated, sealed-for-life ball bearings to support the rotating assembly.
The motor is a 3 HP Premium Efficiency TEFC unit that operates at 1750 RPM, incorporates Aegis grounding, and runs on 380-460V 3PH power with a DOE PEI of 0.48. 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.
