This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a mechanical seal utilizing ceramic and EPT components. The pump incorporates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, protected by a replaceable bronze shaft sleeve. Engineered for 125 PSI, the casing incorporates a wear ring and includes gauge ports for suction and discharge monitoring. The bearing housing uses permanently lubricated, sealed-for-life bearings that allow for maintenance without disturbing system piping.
Powered by a 7.5 HP premium efficiency PMAC motor with a TEFC enclosure, the unit operates at 1750 RPM, utilizes Aegis shaft grounding, and draws 200-230V 3PH power with a DOE PEI of 0.45. The 'S' in the 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.
