This close-coupled end suction pump comprises a cast iron casing with an integrated bronze impeller and a corrosion-resistant bronze shaft sleeve. The dry shaft design eliminates contact between the pump shaft and the circulating fluid to protect internal components, operating at a pressure capacity of 125 PSI without a wear ring. A mechanical seal utilizes a ceramic seat half and EPT rubber, while the assembly incorporates flush seal line taps to allow for the installation of a filter to shield the seal from non-condensable particles. Suction and discharge connections include pressure tappings to facilitate system monitoring and ongoing maintenance.
Powered by a 5 HP premium efficiency ODP motor operating at 3450 RPM with Aegis grounding, this assembly uses a 380-460V / 3PH power supply and holds a DOE PEI rating of 0.45. 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
