Rotolok markets a range of Pipe Couplings ideally suited to pneumatic conveying. The couplings hold the advantage of low cost and quick assembly.
Blo-Line Compression Couplings consist of an outer shell with lips flanges enveloping stiffener bars, an inner sleeve with precision meshing teeth and a gasket with a die cut tooth design to ensure a positive seal. When bolts are tightened, the heavy flanges draw in the outer shell which, in turn, applies uniform pressure on the inner sleeve and gasket to ensure sealing of the line being coupled.
Couplings are also available with lever operation for quicker access to the connected pipes.
For use more hygienic industries such as Food, Chemical or Pharmaceutical applications, Rotolok offer Blo-Line Couplings in Stainless Steel. This allows for a cleaner, more hygienic conveying system and when coupled with the lever operation allows the coupling to be quickly removed and cleaned.
