This end suction pump utilizes a cast iron casing with integrally cast mounting feet and a center-line discharge for positive air venting. The assembly integrates a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve. This dry shaft design prevents contact between the circulating fluid and the shaft, providing a pressure rating of 125 PSI without the use of a wear ring. Mechanical sealing consists of a ceramic seat and EPT rubber to provide durability for the internal rotating components.
Powered by a 5 HP premium efficiency TEFC motor, the assembly operates at 1750 RPM and incorporates Aegis grounding for the 380-460V 3PH power supply, resulting in a DOE PEI rating 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
