This centrifugal end suction pump incorporates a cast iron casing with a center-line discharge for air venting. The unit integrates a stainless steel impeller and a stainless steel shaft, protected by a bronze shaft sleeve to facilitate a dry shaft design. This configuration prevents contact between the circulating fluid and the shaft, supporting a pressure rating of 125 PSI. A mechanical seal constructed with a ceramic seat half and EPT rubber components completes the internal assembly, while the overall build allows for service without disturbing system piping connections.
Powered by a 7.5 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding, the assembly utilizes 380-460V, 3PH power, achieving a DOE PEI rating of 0.49. 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.
