This base-mounted end suction pump utilizes a cast iron casing with a center-line discharge and an integrally cast bronze impeller. The assembly incorporates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. For sealing, the unit utilizes a mechanical seal constructed with a ceramic seat half and EPT rubber, engineered to operate at a maximum pressure of 125 PSI without a wear ring.
The 25 HP Premium Efficiency ODP motor operates at 1750 RPM, integrates Aegis grounding, and accepts 200-230V 3PH power with 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.
