This base-mounted end suction pump utilizes a class 30 cast iron casing with integrally cast mounting feet and is engineered for operation at 125 PSI. The assembly incorporates a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve, which prevents fluid contact via a dry shaft design. A mechanical seal with a ceramic seat and EPT rubber ensures fluid containment, while the casing integrates pressure tappings at the suction and discharge connections to facilitate system monitoring. This configuration allows for maintenance of the mechanical seal and bearing housing without disturbing system piping.
The 7.5 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, accepting a 380-460V / 3PH power supply with a DOE PEI rating 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
