Gentle delivery of cleaning agents

Pumping cleaning agents presents pumps with enormous challenges. In addition to abrasive or corrosive properties, it is not uncommon for foaming behavior to occur. The rotation in the pump can cause the medium to foam up. This often leads to considerable problems and costs during filling at the end of the process chain. Pumps sometimes have to run extremely slowly to prevent the cleaning agent from changing its state and foaming up during pumping. If the cleaning agent has already foamed up during filling, it can lead to overflowing or foaming out of the container. The pumps for cleaning agents belong to the family of screw pumps and are assigned to the CHEMSPIN series.

 

 

Best Practice:

We replaced the existing pump technology for a customer. By spinning the medium in the pump, it was foamed to such an extent that effective filling was no longer possible. Due to the foaming out of the container, the label could no longer be applied to the bottle in the further course of the process. The bottles had to be subjected to additional, unscheduled cleaning. Thanks to the more gentle conveying with screw pumps, the throughput was increased by around 80 % and the process was made significantly more efficient.

 

Further application examples

Adhesives

Adhesives mixed with solvents pose a high risk of cavitation in the conveying process. The challenge is that the slightly boiling solvents generally behave differently to the other components.

Underbody protection

Underbody protection is used to preserve vehicles and machines and constantly presents pump manufacturers with new challenges. However, gentle pumping of formulations with sensitive components such as glass beads is not a problem.

Tanks storage /farms

Filling, emptying or circulation pumping are recurring tasks for tank farm operators. Thanks to their high flexibility, screw pumps can handle a wide range of pumping tasks with just one series.

Paints and varnishes

Pulsation-free conveying and filling of colors can be a real challenge. Pigmented colors are usually extremely sensitive and must be conveyed particularly gently so that pigments are not destroyed.

Cleaning agent

Corrosive or abrasive liquids present pumps with major challenges. Especially when pumping cleaning agents, for example, solids can also be conveyed.
