This close-coupled end suction pump is constructed with a cast iron casing and a bronze impeller to manage fluid transfer. The assembly incorporates a dry shaft design that eliminates contact between the circulating fluid and the stainless steel shaft sleeve, which protects the pump shaft. Mechanical sealing is provided by a ceramic seat and EPT rubber, rated for 125 PSI operation without a wear ring. The design integrates flush seal line taps and pressure tappings on the suction and discharge connections to facilitate system maintenance and monitoring.
The 50 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and accepts a 200-230V 3PH power supply, resulting in 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 utilizes quadratic variable flow control, 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.
