Innovative, flexible mixing ratio control (1)
The dos piston has two motors, one for each mixing component. This allows fine adjustment of the material mixing ratio (e.g. resin and hardener) via the software-based individual control of the two motors.
The advantages: Maximum flexibility and easy handling.
Sensors and control software (2)
An evaluation of the encoder data enables a reliable prognosis of the status of important parameters The pot life of each potting material is automatically stored by software to trigger an automatic warning message if the time is exceeded or a flush shot is taken.
Flushing liquid (3)
The cylinder is automatically flushed with every stroke to prevent deposits on the cylinder wall and wear on the valves/seals.
Flow-optimized material transport (4)
All material guides in the dos piston have been flow-optimized so that potting material can flow trouble-free and with high performance at every point.
Replaceble dispensing head (5)
The dos piston dispensing head can be separated from the lifting unit in just a few simple steps to enable quick maintenance and cleaning work.
Mixing tube with feed screw (6)
A mixing tube with a feed screw is attached at the dispensing outlet to ensure the homogeneous mixing of the components of the potting materials.
The mixing tubes are single-use products made of plastic.
Optional functions:
Equipment for abrasive media.

how dos piston works
The potting compound is fed from material preparation to the dispenser.
The dispenser is filled with the potting materials.
Die Dosierkolben pressen die Vergussmaterialien im exakten Mischungsverhältnis durch den Dosierkopf.
The potting materials are mixed and homogenised at the dispensing outlet in the feed screw.
The complete potting compound is applied to the component providing the best dispensing results.
