Fields of applications

Delivery of acids, bases, lye or other corrosive, harmful or toxic liquids in such applications, where even small leakages are not acceptable and a hermetically sealed pump is required. Delivery of highly pure and sensitive liquids, where contamination must absolutely be avoided.

For example in the following applications:

• Plating and surface coating
• Semiconductor technology and solar cell production
• PCB and electronics manufacturing
• Wastewater and fresh water treatment
• Laboratory equipment and medical technology
• Emission controls and gas scrubbers
• Battery production and energy storage
• High-purity applications, demineralized water, ultrapure water
