This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a bronze shaft sleeve installed over a stainless steel shaft. The assembly incorporates a dry shaft design to prevent contact between the fluid and the shaft, maintaining an operating limit of 125 PSI. Sealing relies on a mechanical seal constructed with a ceramic seat and EPT rubber. This unit provides pressure tappings on both the suction and discharge connections to facilitate system monitoring.
The 7.5 HP premium efficiency ODP motor operates at 3450 RPM, integrates Aegis grounding, and receives power via a 380-460V 3PH supply, resulting in a DOE PEI rating of 0.45. 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
