This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. The design utilizes a dry shaft that prevents contact between the circulating fluid and the stainless steel shaft. A replaceable bronze shaft sleeve covers the shaft, and the assembly integrates a mechanical seal comprised of a ceramic seat half and EPT rubber. The pump casing provides a 125 PSI pressure rating without a wear ring and includes gauge ports for suction and discharge connections.
The motor operates at 20 HP, meets premium efficiency standards, maintains an ODP enclosure, and rotates at 1750 RPM. This assembly integrates Aegis grounding and utilizes a 200-230V / 3PH power supply, achieving 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
