This end suction pump utilizes a cast iron casing with a center-line discharge for air venting and includes a bronze impeller dynamically balanced to ANSI Grade G6.3. The dry shaft design prevents contact between the circulating fluid and the shaft, which is protected by a replaceable bronze shaft sleeve and constructed of stainless steel. A mechanical seal with a ceramic seat and EPT rubber ensures containment during operation, with the assembly rated for 125 PSI and equipped with a wear ring. Integration of flush seal line taps allows for the installation of an external filter to protect the seal from particles.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, accepting 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 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.
