This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a bronze impeller. The assembly utilizes a stainless steel shaft paired with a replaceable bronze shaft sleeve and a dry shaft design that prevents circulating fluid from contacting the internal shaft. A mechanical seal consisting of ceramic seat halves and EPT rubber components facilitates operation at pressures up to 125 PSI. Hydraulically balanced to meet performance standards, the unit integrates gauge ports at the suction and discharge connections to simplify pressure monitoring during system operation.
The pump utilizes a 40 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis Grounding, powered by a 380-460V 3PH electrical supply, yielding 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
