Knowing revolutions per minute is critical to adjusting power to match system requirements.
Motors
Motors are the most common source of power used by pumping systems. This technology is heavily regulated. Pumps by themselves are not variable speed, an option that many systems need to operate with peaks and ebbs during the run cycle, such as power generation. The addition of a variable frequency drive (VFD) gives it that capability.
Choice should be based on load, thrust, lubrication and other specific application needs.
Permanent magnet motor technology gives users an option beyond surface and submersible choices.
Distorted waveforms can cause wasteful heat, more frequent equipment failure and added costs from increased power usage.
Variable mixing can provide a homogeneous process volume, consistent temperature and improved biological contact.
