This base-mounted end suction pump comprises a cast iron casing with an integrally cast mounting foot and center-line discharge configuration for positive air venting. The assembly integrates a bronze impeller, a bronze shaft sleeve, and a stainless steel shaft, utilizing a dry shaft design that prevents circulating fluid contact. Rated for 125 PSI, the construction incorporates a replaceable bronze wear ring and a mechanical seal assembly featuring a ceramic seat and EPT rubber components. The bearing housing utilizes permanently lubricated, sealed-for-life ball bearings accessible without disturbing system piping.
The 5 HP Premium Efficiency TEFC motor operates at 1750 RPM, integrates Aegis Grounding, and functions on 200-230V / 3PH power, resulting in a DOE 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
