This end suction pump incorporates a cast iron casing and a bronze impeller to facilitate fluid movement. The assembly integrates a stainless steel shaft paired with a bronze shaft sleeve, utilizing a dry shaft design that prevents contact between the circulating fluid and the shaft. It utilizes a mechanical seal constructed with a ceramic seat half and EPT rubber, rated for operation up to 125 PSI without a wear ring. The construction allows for servicing without disturbing the system piping.
The 25 HP Premium Efficiency ODP motor operates at 1750 RPM, incorporates Aegis grounding, and receives power from a 380-460V, 3PH electrical supply, yielding 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.
