This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The design integrates a stainless steel shaft paired with a bronze shaft sleeve to maintain a dry shaft configuration, preventing contact between the circulating fluid and the shaft. A ceramic seat with EPT rubber elements comprises the mechanical seal, which operates at a maximum pressure of 125 PSI without a wear ring. The volute utilizes center-line discharge for air venting and includes pressure tappings for suction and discharge connections.
This 3 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis shaft grounding and a 380-460V 3PH power supply, achieving 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 an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
