This base-mounted end suction pump utilizes a class 30 cast iron casing with integrally cast mounting feet. The assembly integrates a bronze impeller and a bronze shaft sleeve covering a stainless steel shaft. A dry shaft design prevents circulating fluid from contacting the shaft. The mechanical seal comprises ceramic seat halves and EPT rubber, rated for 125 PSI without a wear ring. Pressure tappings at the suction and discharge connections allow for gauge installation, while the centerline discharge configuration facilitates positive air venting.
This 25 HP premium efficiency TEFC motor operates at 3450 RPM, integrates Aegis grounding, and accepts 380-460V / 3PH power with 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 is configured with a fused disconnect without bypass and holds a NEMA Type 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
