This end suction pump utilizes a cast iron casing with a stainless steel impeller and a stainless steel shaft. It incorporates a replaceable bronze shaft sleeve and a dry shaft design that prevents fluid contact with the shaft, rated for 125 PSI. A mechanical seal with a ceramic seat and EPT rubber ensures pump integrity. The assembly is constructed with integral mounting feet and utilizes center-line discharge for air venting.
The pump assembly is powered by a 1.5 HP premium efficiency TEFC motor operating at 1750 RPM, which integrates Aegis grounding and utilizes a 380-460V 3PH power supply, with a DOE PEI 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
