Dynamic laminar (disk) friction pumps. Applications of pumps ONL
Overview of the nomenclature, designs of ONL pumps and various schemes for installing equipment and strapping in the pipeline network. Features of die-welded constructions of monoblock laminar (disc) pumps for viscous liquids (up to 300,000 cSt). The history of design development, implementation and application of pumps in various industries. Replacement of volumetric pumps with dynamic friction pumps. Graphs and examples of the use of pumps in the food, chemical, paper, biological industries and water utilities are given.
