This close-coupled end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly integrates a bronze shaft sleeve and a dry shaft design that eliminates contact between the circulating fluid and the pump shaft. A mechanical seal utilizes a ceramic seat and EPT rubber to maintain operation at pressures up to 125 PSI. This pump includes flush seal line taps and pressure tappings on suction and discharge connections to monitor system performance.
The motor operates at 20 HP with a Premium Efficiency rating and TEFC enclosure at 1750 RPM, utilizing Aegis Grounding on a 380-460V, 3PH power supply, resulting in a DOE PEI 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 an electro-mech bypass and main fused disconnect and holds a NEMA 1 / IP 21 enclosure rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
