This centrifugal end suction pump integrates a cast iron casing with a bronze impeller, bronze shaft sleeve, and a stainless steel shaft. It incorporates a dry shaft design to isolate the shaft from circulating fluid and utilizes a mechanical seal constructed with a ceramic seat and EPT rubber. The assembly holds a 125 PSI pressure rating and includes a wear ring to facilitate maintenance. The pump casing provides for positive air venting through its centerline discharge and is drilled for suction and discharge gauge ports and a bottom drain.
Powered by a 5 HP Premium Efficiency ODP motor operating at 1750 RPM, the assembly utilizes Aegis grounding and functions on 380-460V / 3PH power with a PEI 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
