This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller to facilitate efficient fluid movement. The assembly incorporates a stainless steel shaft protected by a replaceable bronze shaft sleeve in a dry shaft design that prevents contact between the circulating fluid and the shaft. A mechanical seal composed of ceramic and EPT provides reliable sealing performance at system pressures up to 125 PSI. The casing incorporates a replaceable wear ring and provides center-line discharge for positive air venting, while the overall design allows for servicing without disturbing the system piping.
Powered by a 20 HP premium efficiency TEFC motor operating at 1750 RPM, this pump utilizes Aegis grounding and accepts a 200-230V 3PH power supply with a DOE PEI rating of 0.48. 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
