This base-mounted end suction pump integrates a cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design with a stainless steel shaft and replaceable bronze shaft sleeve to prevent fluid contact. A ceramic mechanical seal with EPT rubber maintains integrity at 125 PSI without a wear ring. The unit incorporates center-line discharge for venting and pressure tappings on suction and discharge connections. Permanently lubricated, sealed-for-life ball bearings support the bearing housing.
The motor operates at 25 HP, utilizes a premium efficiency design with a TEFC enclosure, achieves 3450 RPM, integrates Aegis grounding, and accepts 380-460V / 3PH power, providing 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.
