This base-mounted end suction pump utilizes a cast iron casing with an integrally cast mounting foot to support hydraulic operations. The internal assembly consists of a bronze impeller paired with a bronze shaft sleeve covering a stainless steel shaft, facilitating maintenance while isolating the shaft from circulating fluids through a dry shaft design. Engineered for pressure ratings up to 125 PSI, the assembly integrates a mechanical seal constructed with a ceramic seat and EPT rubber components.
Powered by a 5 HP premium efficiency TEFC motor operating at 3450 RPM, the assembly includes Aegis grounding and utilizes a 380-460V / 3PH power 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.
