Rotary pumps are designed for the constant pressure from a direct waterline connection. They also have other benefits over vibratory pumps, including being quieter, lasting longer due to more robust design, and in blind taste tests they do better than vibratory pumps. We have a complete range of home espresso machines with rotary pumps, ranging from the cheapest options to the more expensive high end machines for the very serious coffee aficionados.
Pros of Rotary Pump Espresso Machines
- Best for direct water line connected machines as they are designed to handle constant water line pressure vs most vibratory pump which are not designed for constant water line pressure
- Blind tastes have been done comparing rotary vane pumps to vibratory pumps and rotary vane pumps tend to do better than vibratory pump machines. This is due to the pressure profile during extraction and the pulsing pressure vs steady pressure.
- Rotary pumps are quieter than vibratory pumps, and in some cases, a lot quieter.
- Rotary pumps are generally quite a bit more robust in terms of design than vibratory pumps, with a lot more metal and tend to larger than vibratory pumps. For this reason rotary pumps tend to be less prone to failure and tend to last longer.
Cons of Rotary Pumps
- The biggest con of rotary vane pumps is that, since they are more robust pumps and take more metal to make, they cost more to produce and, therefore, espresso machines that have rotary vane pumps tend to cost quite a bit more than comparable espresso machines that have vibratory pumps.
- While rotary pumps tend to last longer, when they do need to be replaced, they cost more to replace vs relatively cheap vibratory pumps.
Difference In Extraction Between Rotary and Vibratory
Rotary pumps can reach full pressure almost immediately, compared to vibratory pumps that take longer to build up to full pressure. As long as coffee is tamped and distributed correctly, espresso machines with rotary pumps tend to hold pressure at a consistent level during extraction. As an example, a rotary pump espresso machine may hold the brew pressure at 8.5 bars and keep it there during the entire extraction. A vibratory pump will have more pulsation during extraction. As an example, the level of pressure may jump and down between 8 bars and 9 bars during the entire extraction.
