This base-mounted end suction pump utilizes a class 30 cast iron casing with integrally cast mounting feet and a bronze impeller. The design integrates a dry shaft with a stainless steel shaft and shaft sleeve, preventing fluid contact with the internal shaft assembly. A mechanical seal constructed with EPT rubber and ceramic seats manages the 250 PSI operating pressure. This unit incorporates pressure tappings on the suction and discharge connections to facilitate system monitoring, while the bearing housing contains permanently lubricated sealed-for-life ball bearings. The assembly allows for service without disturbing connected piping.
The 40 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, with a power supply of 380-460V / 3PH, achieving a DOE PEI of 0.44. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
