Description
One hopper across a shared grinder platform
The WPM ZD-12, ZD-15 and ZD-16, the Sunbeam EM0480 and EM0440, and the Graef CM7 series are sold under different brands in different markets but share enough of their build for one hopper to fit them. The WPM ZD-15 is a conical burr grinder offering around 25 grind settings; the Sunbeam EM0480 is a conical burr grinder rated at 150 W.
Burr diameters are not stated on this page. Published figures for these models are inconsistent between retailers, and a wrong number is worse than no number.
What the hopper changes
These are domestic grinders, which means they are usually the only grinder in the house — espresso one morning, filter the next, a gift bag of something different the week after. The stock bean hopper has to be emptied for every one of those changes.
Replacing it with a single dose hopper removes that step: you weigh in the beans for the brew you are making and grind those. Pressing the silicone bellows afterwards clears grounds from the burr chamber, which matters most when the next coffee is deliberately different from the last.
Version 3
Every unit we ship today is Version 3. The bellows is a custom branded, factory moulded silicone part — it is no longer 3D printed, as our earlier versions were.
How it is made
- 3D printed: lid, lid lock ring, connector, air-leak prevention gasket
- Factory machine moulded: silicone bellows
Materials
- Lid, lock ring, connector: PETG hard plastic
- Air-leak prevention gasket: TPU — material info

Fitting
This hopper is made for the grinder named on this page. Fit tolerances vary between units and production runs, so minor adjustment may be needed to seat it perfectly on your grinder. Every unit is covered by our 2 year warranty.
