It is possible to drain the liquid while the shaft is rotating, and it's okay to be in a free-running state.

The newly developed product allows for stirring with a pipe as the stirring shaft, enabling liquid to be extracted through the upper rotary joint and pump of the shaft while stirring, and also allows for transfer. Liquid can be drained while the shaft is rotating, and it is fine even if it goes into a free spin state. Additionally, it is also possible to inject liquid in the reverse direction. Previously, the shaft was tightened with mounting set bolts, which often caused scratches on the shaft and led to issues with the shaft becoming stuck. However, with the adoption of the new ETP method in this product, there are no scratches on the shaft at all. For more details, please contact us or refer to the catalog.

It can be raised and lowered simply by lightly pressing the mixer up and down with your hand.

Traditionally, when using air motor stirrers or electric variable stirrers, the stirrer was installed on a stand and lowered into the stirring container for use, then lifted back up and secured with a lever after use. This required effort when the stirrer was used frequently, and in the case of the ETP method, cleaning was necessary. The newly released "Easy Lift Stand" allows for easy insertion into and removal from the container by simply pushing the stirrer up and down lightly with your hand. Models are available for LZB22-CB5, LZB33-B2.5, and LZB42-B2/LZB46-B2/LZB54-B2. For more details, please contact us or refer to the catalog.
