This end suction pump utilizes a class 30 cast iron casing with center-line discharge and integrally cast mounting feet. The assembly incorporates a bronze impeller and a stainless steel shaft, protected by a dry shaft design that eliminates fluid contact with the shaft, which is covered by a replaceable bronze shaft sleeve. A mechanical seal with EPT rubber and a ceramic seat manages pump sealing, while pressure tappings exist at both suction and discharge connections. Rated for 125 PSI, the construction allows for service without disturbing system piping.
The 50 HP Premium Efficiency TEFC motor operates at 1750 RPM, integrates Aegis Grounding, and utilizes 380-460V / 3PH power supply, resulting in 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
