Lobe Pump DOSSER LR1 Series Pumps for the food and pharmaceutical materials DOSSER LR1 Series pump is ideal for pumping viscous liquids SS 316 thick likeglue, water,mayonnaise, chocolate sauce and yogurt, etc. There are many modelsto choose from. Pipe sizes ranging from 1 inch to 4inches.
Rotor Pump is also named roots pump, colloidal pump,high concentration pump, etc, It depends on two synchronic rotators. The two rotators are driven by a pair of outer-set synchronic gear boxes and the transmission shaft. They move synchronically in counter-clockwise directions. Which consequently,builds up high vacuum capacity and emission pressure. The two rotators divider the rotator room into many smaller parts and the works according to I II III IV (as below). When it revolves to position I ,only entrance if filled with medium;when it revolves to position II encloses part of the medium, when arriving at position. III ,room III encloses medium,and finally it goes to position IV ,then entrance and export housing are interlinked and the medium is transported to the ourlet. As this process is repeated,medium is to be gone out by unfailing transportation.
