This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller to facilitate fluid movement. The assembly integrates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable stainless steel shaft sleeve. Mechanical sealing is provided by a ceramic seat with EPT rubber elements. The pump maintains a pressure rating of 125 PSI.
The system utilizes a 25 HP Premium Efficiency ODP motor operating at 1750 RPM with Aegis Grounding, configured for 380-460V / 3PH power, and achieves a DOE PEI 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.
