Before we begin it is important to note that this information only applies to pressurized or pump machines. Gravity fed machines do not use pumps because you pour the product mix into the hoppers which sit on top of the machines and freezing cylinders. When you pour the mix into the hoppers, gravity pulls the mix into the freezing cylinders.
Horizon Pump. The best way to tell the difference is to open up the machine. The horizon pump is easily distinguishable by its use of 2 sets of tubes per barrel (used as hopper below the machine in large full standing models) as well as the circular face plates that create a semicircle shape with the tubes. The horizon pump has a more intricate assembly in which it has a variety of O rings instead of plastic pieces. Since the horizon pump uses a more complicated system with rubber pieces, then it is much more complicated to disassemble, clean, and reassemble. Since it is more complicated to take apart and put back together you usually need some training (typically 3 session) from a Taylor company technician. The extensive use of O rings and other rubber parts makes the machine more reliable and less likely to mess up compared to the simplified pump (although both pumps have a very small percentage of mistakes).
