This centrifugal end suction pump incorporates a cast iron casing with center-line discharge and a bronze impeller. The assembly utilizes a stainless steel shaft protected by a replaceable bronze shaft sleeve and a dry shaft mechanical seal design constructed with ceramic and EPT components. Rated for 125 PSI, the construction provides a rigid hydraulic foundation for the fluid system.
Powered by a 5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding and a 380-460V / 3PH power supply, this unit achieves a DOE PEI rating of 0.44. 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. Parallel pumping and multi-pump control functions are integrated into the drive operations. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
