This centrifugal end suction pump utilizes a cast iron casing with a bronze impeller and a bronze shaft sleeve on a stainless steel shaft. The dry shaft design prevents contact between the circulating fluid and the shaft. A mechanical seal constructed with a ceramic seat and EPT rubber ensures fluid containment at pressures up to 125 PSI. An internal wear ring maintains pump efficiency during operation. The assembly comprises integrally cast mounting feet for structural stability and incorporates gauge ports at both the suction and discharge connections to monitor system performance.
This pump operates with a 7.5 HP premium efficiency ODP motor at 1750 RPM, integrated with Aegis grounding and powered by a 380-460V, 3PH supply, achieving 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 an electro-mechanical bypass, main disconnect, and 5kA SCCR, and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
