Elmo Rietschle S-VSA TWISTER 330 – outdated model
The S-VSA TWISTER 330 is no longer part of the current Elmo Rietschle range; the manufacturer names no successor. The next larger current Elmo Rietschle screw pump in our range is the S-VSI 301. The screws run without contact; the pump is water-cooled, and only the gear contains oil. Elmo Rietschle cited easy servicing and corrosion-resistant versions with various coatings, and recommended the range for solvent recovery and drying processes. Elmo Rietschle listed it in version 330 (30). The technical data are taken from the Elmo Rietschle catalogue “S series” (2010 edition). We do not list order numbers for this model; the type designation on the data plate is what counts.
