This end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a replaceable bronze shaft sleeve and a dry shaft design that prevents the circulating fluid from contacting the pump shaft, supporting a 125 PSI pressure rating without a wear ring. The assembly utilizes a mechanical seal composed of a ceramic seat half and EPT rubber.
The 40 HP premium efficiency TEFC motor operates at 3450 RPM and incorporates Aegis grounding, a power supply of 380-460V / 3PH, and a DOE PEI rating of 0.46. The 'S' in the SFI 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.
