This base-mounted end suction pump utilizes a class 30 cast iron casing with center-line discharge and a bronze impeller. The assembly incorporates a dry shaft design, which prevents contact between the circulating fluid and the stainless steel shaft. A bronze shaft sleeve protects the shaft while providing surface area for the mechanical seal, which consists of ceramic seat halves and EPT rubber. The design is rated for 125 PSI operation without a wear ring and integrates gauge ports at both suction and discharge connections for system pressure monitoring.
This unit utilizes a 40 HP premium efficiency TEFC motor operating at 3450 RPM, equipped with Aegis grounding and powered by 380-460V 3PH input, resulting in a DOE PEI 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
