This base-mounted end suction pump integrates a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly incorporates a dry shaft design that prevents contact between circulating fluids and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. A ceramic and EPT mechanical seal provides containment under a maximum operating pressure of 125 PSI. This configuration allows for maintenance on the mechanical seal and bearing housing without disrupting system piping.
The 25 HP premium efficiency ODP motor operates at 3450 RPM and utilizes Aegis grounding on a 380-460V 3PH power supply, achieving 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
