This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller. The design utilizes a dry shaft configuration with a bronze shaft sleeve, facilitating maintenance by eliminating fluid contact with the pump shaft. Pressure tappings on the suction and discharge connections enable performance monitoring, while flush seal line taps provide the option for filter installation to protect the mechanical seal. The seal construction uses a ceramic seat half and EPT rubber, handling pressure up to 125 PSI without a wear ring.
This assembly operates with a 3 HP premium efficiency ODP motor at 1750 RPM, incorporating Aegis grounding and a power supply of 200-230V / 3PH, maintaining a DOE PEI rating of 0.45. 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.
