Progressive cavity pumps – Volumetric dosing systems
Passion for technology & quality
Purely volumetric dispensing
High precision & absolute repeatability
Volumetric dosing pumps, metering systems, precision volume dosing devices, dispensers, mixers, dosing systems, or delivery machines are based on the endless piston principle. Among others they are used for adhesives, paints, soldering pastes and sealants. And this in the most divers industries, like medical technology, but also with cosmetics such as mascara and vaseline, or in the food industry for filling sauces, flavours etc.
All materials, which in certain cases can have a viscosity of up to 7,000,000 mPas, are conveyed and dosed practically free of pulsation and with an extremely low shear force. You will receive comprehensive advice for every application and extensive tests will be carried out for particularly complex challenges. Our dosing pumps and dosing systems are optimally adjusted to the application case in question. Due to this, the are providing the best possible options for cleaning them in food applications, for example.
Our progressive cavity pumps focus on dosing (dosing technology, metering technology), applying, filling, mixing, emptying and unloading, preparing or processing (degassing or barrel emptying, for example) a wide range of different liquids or pastes. Our core competence really comes to the fore with fluids which are high-viscosity, solids-loaden, abrasive or/and shear-sensitive. With our brand preeflow we enable high-precision dispensing of smallest amounts in the µl-range.
How our technology works:
Why to choose volumetric dosing technology:
Progressive cavity pump work without any valves – compared to piston pumps, time pressure systems or gear pumps. This fact reduces the amount of wear and tear parts and increases the level of accuracy at the same time. If the dispenser inlet is properly supplied, the pump works endlessly without any refill steps in between. This enables a continuous production.
Particularly low-density materials require an extremely gentle handling. The use of a stainless-steel spindle and an individually aligned elastomer decreases the level of shear to a minimum. Microspheres won’t be destroyed during processing.
The possibility to perform a suck back (dispenser turns in reverse direction) facilitates a break of the thread after dispensing. This also increases the dosing accuracy to 99%. Our products are specially adapted to your material to be processed and also integrated into your production process. For efficient product handling during the removal, feeding and dosing of 1- and 2-component materials – including intuitive control technology.
