Open-Head Drum Mixer MBEO-500 (Top-Clamp Mount)
The MBEO-500 is the drum mixer for open-head drums — the kind with a bolted lid you can take off completely so the whole top of the drum is accessible. It clamps around the drum rim with a top clamp and drops a full-size folding propeller straight into the open drum. Different mount than the lid-mount MBEP series, and a different customer base.
Most MBEO-500 units we ship go to furniture coating shops and small paint manufacturers. The typical job is mixing water-based primers, light alkyd paints or wood stains in steel or fibre drums between batches. Some food processors use it too, when they buy ingredients in open-head steel drums and need to re-homogenise before transferring to the production line.
What this version handles
- Water-based paints, primers and stains in furniture coating shops.
- Small paint manufacturers — colour matching, tinting, batch finishing in open-head drums.
- Light alkyd lacquers and wood treatment products (non-Ex applications).
- Food ingredients delivered in open-head steel drums — oils, syrups, concentrates.
- Cleaning agents and detergent concentrates in 200 L steel drums.

How to know if your drum is open-head
If the top of the drum is a separate piece held on by a metal ring with a bolt or quick-release clamp, it is an open-head drum. You can take the whole top off. The MBEO-500 clamps around the now-exposed rim. If instead your drum is a sealed plastic chemical drum where you only see a small lid you twist off, that is not an open-head drum — you need the lid-mount MBEP-500 instead.
