Macap CPS Dynamometric Tamper

The MACAP CPS (Constant Pressure System) automatic espresso tamper is an innovation for streamlining espresso production. It helps conform all users to utilize the same tamp pressure. Using a lever, this tamper applies uniform and level pressure to the ground espresso in a group handle. The result is a predictable and consistent extraction; a leap forward in simplifying traditional espresso preparation.

  • Constant dynamic pressure: 55 pounds (25 kilograms)per manufacturer spec’s.
  • Tamper diameter plates: (1) 51 mm, (1) 57.5 mm.


  1. The Macap CPS Twist cannot tamp in rapid succession. For double (or triple) tamping in succession in the same portafilter, you need raise the handle to the top position before re-tamping.
  2. This tamper may arrive with a little excess grease around the mechanism or surrounding portion of the bag. You can use a dry cloth to to clean off any excess. This will not have any impact on the operation of the grinder.
  3. The tamping pressure is adjustable, but Macap does not provide instructions. In addition, there is no way to determine the exact pressure to adjust to.
  4. Concept Art bases can screw onto this tamper. It leaves a gap but it is a secure fit.

      Q Will this work with a 58mm portafilter size? answer now

      Yes, but there can still be a little space on the sides as it depends upon the basket.

      Yes. It was made at 57.5 for those who have filter baskets that slope inward as the tamper gets pushed downward.

      We suggest you review the diagram to learn how to take the piston apart. It is not easy to take apart and put back to together. Yes, the screw can strip.

      It could be a bad spring or other failed component. The tamper would need to be taken apart and evaluated to determine which part has worn or failed. Part numbers can be determined using the diagram, and then searching for the part number on our web site.

      Sorry, Macap does not recommend adjusting the pressure, and this is why there is no indication of the manual to adjust it. The pressure is certified by Illy Caffe as the unit was originally designed for them.

      Answered by the admin Yes, 55 pounds is the maximum. This design was actually requested by Illy when this tamper was being developed. These do sell out quickly.
