This base-mounted end suction pump comprises a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft, while the dry shaft design ensures no contact with circulating fluid. The unit incorporates a mechanical seal constructed with ceramic seat halves and EPT rubber. This assembly handles pressures up to 125 PSI without the use of a wear ring and utilizes flush seal line taps to prevent particle accumulation.
This assembly runs on a 5 HP Premium Efficiency TEFC motor at 3450 RPM with Aegis shaft grounding, receiving power from a 380-460V 3PH supply, with a DOE PEI rating of 0.47. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
