This base-mounted end suction pump comprises a cast iron casing with a center-line discharge for positive air venting. It utilizes a bronze impeller balanced to ANSI Grade G6.3, a stainless steel shaft, and a replaceable bronze shaft sleeve. The dry shaft design prevents contact between the circulating fluid and the shaft, providing a pressure rating of 125 PSI. A mechanical seal with a ceramic seat and EPT rubber components isolates the assembly. Integrated flush seal line taps allow for the installation of a filter to protect the seal from non-condensable particles. The assembly has pressure tappings on the suction and discharge connections for monitoring.
This pump utilizes a 30 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis Grounding, powered by 380-460V / 3PH supply, and holds a DOE PEI rating of 0.46. 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.
