This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design that prevents fluid contact with the stainless steel shaft, which is covered by a replaceable bronze shaft sleeve. A mechanical seal comprising a ceramic seat half and EPT rubber components maintains system integrity at a maximum operating pressure of 125 PSI.
The 20 HP premium efficiency ODP motor operates at 1750 RPM and incorporates Aegis grounding, functioning on a 200-230V, 3PH power supply with 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 mechanical disconnect without bypass and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
