A positive displacement pump can be a convenient solution when a centrifugal pump is no longer practical for the current situation. For example, these centrifugal pumps cannot pump viscous liquids. A positive displacement pump presents the solution in such a case!
Displacement Pump Operation
These pumps use a so-called displacement body. This leads to a repeated back-and-forth movement of a section within the working chamber. Whenever this space is open, liquid flows into the chamber. If the area is closing, the liquid can be discharged. This method allows a positive displacement pump to be used waterless and self-priming.
Displacement pump or centrifugal pump?
Usually, a positive displacement pump can be used whenever a centrifugal pump is no longer practical to use. This can be the case, for example, when your job requires specific suction requirements or precise dosing. However, there is an overlap between the usability of a positive displacement- and a centrifugal pump. For this reason, you may select a positive displacement pump, while a centrifugal pump might have been more fitting. Because the correct choice can avoid this disappointment, the experts at IB Pompen are always ready to provide you with appropriate advice! That is why you can contact us without any obligation.
