Packo CM Series Colloid Mill Pumps

The CM series is a hygienic colloid mill featuring a geared rotor and stator made of electro-polished duplex stainless steel.

This mill is designed to precisely grind particles in suspension and achieve repeatable results. The grinding process takes place in the adjustable ring gap between the stator and rotor. The gap can be adjusted by changing the axial position of the rotor, thus increasing the grinding precision.

Key Features

✔ Rotor and stator containing two grinding zones.
✔ Ability to mix liquids simultaneously thanks to high shear forces.
✔ Precise and controlled grinding with adjustable gap.
✔ Hygienic design, an ideal solution for the food and pharmaceutical industries.

With these features, CM series colloid mills are an excellent choice for particle grinding and homogeneous mixing of liquids in the food, pharmaceutical, biotechnology, and chemical industries.
