This base-mounted end suction pump incorporates a cast iron casing with a bronze impeller and a stainless steel shaft. The assembly utilizes a bronze shaft sleeve and a dry shaft design that prevents circulating fluid from contacting the shaft. It integrates a mechanical seal constructed with a ceramic seat and EPT rubber, rated for 125 PSI. This centrifugal unit allows for service without removing system piping and includes pressure tappings on the suction and discharge connections.
Operating with a 25 HP Premium Efficiency TEFC motor at 3450 RPM, the assembly incorporates Aegis grounding on a 380-460V / 3PH power supply, yielding 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.
