This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a dry shaft design with a replaceable bronze shaft sleeve that prevents the circulating fluid from contacting the shaft. The mechanical seal utilizes a ceramic seat half with EPT rubber and is rated for 125 PSI operation without a wear ring. This pump integrates into systems with multi-pump control and parallel pumping capabilities.
This assembly utilizes a 25 HP Premium Efficiency TEFC motor operating at 3450 RPM with Aegis Grounding on a 200-230V / 3PH power supply, achieving a DOE PEI rating of 0.48. 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.
