This base-mounted end suction pump incorporates a cast iron casing with a bronze impeller. The assembly utilizes a dry shaft design to prevent fluid contact, employing a stainless steel shaft covered by a replaceable bronze shaft sleeve. A mechanical seal serves as the primary closure, constructed with a ceramic seat and EPT rubber. This hydraulic configuration supports a 125 PSI pressure rating without a wear ring.
The 20 HP Premium Efficiency TEFC motor operates at 3450 RPM with Aegis Grounding, utilizing 380-460V / 3PH power, and achieves a DOE PEI rating of 0.47. 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.
