![]() PID, which stands for Proportional Integral Derivative, is a type of temperature control that is created when the system constantly monitors the water temperature and pressure and makes small adjustments to keep your machine where you want it to be.

This is when hot water is constantly cycled through the group, which leads to a more consistent temperature but also means longer heat-up times. If a machine has an E61 group, it means that the group head is heated using thermosiphoning. Rotary pumps also get to full pressure more quickly. Rotary pumps are considered to be commercial grade and are much quieter than their counterpart, the vibration pump. Many find this to be more convenient since it means you won’t have to empty the drip tray or refill the water reservoir, so if this is a feature you want be sure to choose a plumbable machine. In addition, most commercial or home espresso machines with rotary pumps are plumbable and can be connected to a water line in your home.

On the other hand, rotary pumps are usually quieter, though there can still be rattling or noise during the brewing process. Vibration pumps are often louder as they can cause rattling due to the vibration during the brew process. The difference between a rotary and vibration pump isn’t just the engineering side of things – there’s a noticeable difference for the user as well.
