VPM-100 Vacuum Power Wedger

Call for Price


Stainless Steel: Shaft, augers and paddles of stainless steel, along with an aluminum mixing/pugging chamber ensures rust-free clay processing.

Large Hopper: The oversized hopper door allows for easy loading of up to 250 lbs. of clay per batch.

Batch Mixing Capability: Full batch mixing and blending capability allows for moisture adjustment before pugging.

Pugmill Output: Switch to PUG after a batch is completely mixed, and the Power Wedger unloads itself in the form of 4″ diameter deaired logs (standard).

Vacuum Deaired: Each batch can be deaired by starting the vacuum pump during the last stage of mixing, leaving an air-free product when pugged out (no need to run the clay through the pugmill multiple times). Once the entire batch of clay has been deaired, switch the pugmill to PUG, and press start. Any remaining deaired clay in the machine can be stored for later use without having to remix or deair. Our patented vacuum design (Click here for full list of patents) allows us to deair the entire batch of clay without the use of cumbersome vacuum/shredding screens, or down time due to a clogged pugmill! No other mixing pugmill on the market matches the Peter Pugger’s effectiveness at deairing clay. We guarantee it!

Sealed Chamber: Here in our Northern California Factory, each pugmill casting has precision CNC machined o-ring grooves incorporated into them which allows the pugmill to effectively store moist clay indefinitely! No other pugmill on the market provides this level of precision when it comes to properly sealing all pugmill surfaces.

Intellectual Mixing Technology: Real-time monitoring of clay consistency can be accomplished while mixing. Similar to an automatic transmission, the Pugger-Mixer can automatically speed up or slow down based on the hardness of the clay being processed. The operator can also control the speed by controlling the variable speed knob.

Patented Vacuum Chamber: The Patented Vacuum Chamber serves as a separation chamber between the processing chamber (where clay is mixed and pugged) and the gear drive system. In the event the pugmill is overfilled, the excess clay is collected in the vacuum chamber where it can be easily accessed and redirected back into the processing chamber in time for the next batch (if necesary). The Vacuum Chamber door is designed to disengage before excess clay can generate enough pressure to damage the gear drive system. This is a key design feature for mixing pugmills where clay is being forced up against the rear of the processing chamber during the mixing cycle. Peter Pugger is the only mixing pugmill to provide extra protection against vacuum and bearing seal exposure resulting in maintenance free operation .

Variable Speed Control: This allows the operator the ability to speed up or slow down the pugmill. This is especially useful when extruding through dies. Because of the back pressure generated by a large amount of clay being forced through a small orifice, the speed control allows the operator to slow the pugging as required. In turn, perfect deaired configurations are easily extruded through the Pugger-Mixer. There are additional advantages if you are a “single potter studio”. The ability to slow the pugging allows for time to place pugged clay into containers or bags.

Corrosion Resistant: Peter Pugger now offers a corrosion resistant models (stainless steel) for potters using porcelain and white stoneware clay bodies with soda spars.

On Wheels: The VPM-100 comes with 8″ diameter wheels. It is easily transported for cleaning and storage.

Work Surface: The motor and drive are enclosed for protection, cleanliness and safety. A 24″ x 20″ cleanable work surface is provided on top for convenience of the operator while loading.


The Power Wedger is the most versatile studio clay processing machine on the market today. It can perform a variety of functions efficiently, transforming clay in any form to a usable product.

Some examples:

  • Mix moist clay from powder and water.
  • Reclaim scrap – wet or dry.
  • Blend two or more different bodies.
  • Add materials (wet or dry) to an already moist body.
  • Adjust moisture of an already wet body.
  • OR just mix 25 lb. bags of clay – literally warm the clay by mixing it.

When the clay is adequately mixed, it can be deaired with vacuum and pugged out in the form of logs ready for use.

“The Vacuum Deairing Pugger-Mixer”

Comes equipped with 240V electrical for standard service.

With the growing demand for high quality deaired clay for high production applications, the newly released VPM-100 carries a colossal “bang-for-the-buck” as the largest Vacuum Dearing Mixing Pugmill on the market today. Known as a “working mule”, the VPM-100 leverages off the PM-100 design originally unveiled in 1975. However, Peter Pugger has incorporated a “chainless”, maintenance free geardrive system, state-of-the-art VFD technology, updated vacuum chamber and robust auger design that embellishes the quality and performance that customers around the world have come to expect.
