This end suction pump utilizes a cast iron casing and a bronze impeller to manage fluid flow, while a stainless steel shaft maintains structural integrity. The assembly integrates a dry shaft construction, which protects the shaft from contact with the circulating fluid, and incorporates a replaceable bronze shaft sleeve. For fluid containment, the pump employs a mechanical seal configured with ceramic seat halves and EPT rubber, providing a pressure rating of 125 PSI without a wear ring. This unit relies on a bearing frame equipped with permanently lubricated, sealed-for-life ball bearings to support hydraulic operations.
The assembly utilizes a 2 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding on a 380-460V 3PH power supply, with 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.
