Mini metering pumps in special pump design
We supply dosing pumps for the chemical industry. The pumps are available in different versions. On the one hand we offer mini dosing pumps for fine dosing, on the other hand dosing pumps for high throughputs of organic or inorganic chemicals. For particularly demanding applications, we also work with our customers to develop special solutions for their needs. For example, we have developed pumps made of ceramic materials for particularly aggressive alkalis and high temperatures. For another customer, we developed a submersible pump that is used in a tank to pump liquid sulfur.
