This base-mounted end suction pump comprises a cast iron casing with an integrally cast center-line discharge and a bronze impeller. The assembly integrates a stainless steel shaft protected by a replaceable bronze shaft sleeve utilizing a dry shaft design that prevents contact with circulating fluid. It is constructed with a mechanical seal utilizing ceramic and EPT materials to maintain performance up to 125 PSI. This pump provides pressure tappings on suction and discharge connections to allow for monitoring and maintenance without disturbing system piping.
Power is provided by a 50 HP premium efficiency ODP motor operating at 1750 RPM with Aegis grounding on 380-460V / 3PH power, maintaining a DOE PEI rating 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.
