This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a hydraulically balanced bronze impeller. It incorporates a stainless steel shaft protected by a replaceable bronze shaft sleeve and a dry shaft design that prevents fluid contact with the rotating assembly. The mechanical seal utilizes a ceramic seat half and EPT components, supporting operational pressures up to 125 PSI. This centrifugal single-stage unit relies on permanently lubricated ball bearings within a cast iron housing to maintain alignment and facilitate field maintenance without disturbing system piping.
This assembly integrates a 3 HP Premium Efficiency ODP motor operating at 1750 RPM, which utilizes Aegis grounding and runs on 380-460V / 3PH power, resulting in a DOE PEI 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
