Vertical Turbine Pumps, Deep Well Figure 1. The general arrangement of a three phase waveform. Vertical Lathe Model 342A Single Stage End Suction Close-Coupled Vertical Turbine Frame-mount Centrifugal Pumps Super T Series® Engine Driven Utah Lake Cascade Pump Gorman-Rupp SF Series® Submersible Solids-handling Pump Schlumberger Pump Assembly Ultra V Series® and UltraMate® Impeller wear ring Utah Lake Cascade Pump 80 Series® Engine Driven National Pump Vertical Turbine Pumps, API 610 Custom shapes cut from raw materials. Figure 3. Three phase power has three identical sine waves overlapping at an offset of 2π/3 radians or 120°. When one phase reaches an x-intercept or node the next phase is only 30° and approximately 5.6 milliseconds from reaching its crest. 380 Series Vertical Inline Pump with VFD Photo courtesy of On the slopes Horizontal Lathe Nickerson Field Crew “NSF/ANSI 61.” NSF RSS. The Public Health and Safety Organization, n.d. Web. 07 June 2017. Figure 2. A simple sine wave with a period of 360° and an amplitude of 1. In single phase power the x-intercepts are 180° from each other. A full period is 360°. A single phase motor has a crest approximately every 16.5 milliseconds giving the motors a tendency to vibrate more, which may contribute to a shortened bearing life.
