This base-mounted end suction pump incorporates a cast iron casing with a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. The dry shaft design prevents fluid contact with the shaft, allowing for operation at pressures up to 125 PSI without a wear ring. A mechanical seal utilizes a ceramic seat half and EPT rubber to maintain system integrity. Center-line discharge construction assists with air venting, and the internal design allows for serviceability without disturbing the connected system piping.
The assembly operates with a 25 HP premium efficiency ODP motor at 1750 RPM, utilizing Aegis grounding and a 380-460V 3PH power supply, resulting in 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.
