KNF is equipped to meet the demands of project business. The company supplies the pump solutions needed, and thanks to fl exible production systems is also able to manufacture them in small quantities.

A team of engineers and designers with many years of experience and detailed knowledge of the applications is available to advise and support you.

Our duty is to meet your quality standards. Developing, designing and producing process pumps in Germany and Switzerland ensures compliance with rigorous quality requirements and standards.

QUALITY CONSULTATION AND DEVELOPMENTPROCESS UNDERSTANDING SPECIFICATION DOCUMENTATION

Comprehensive documentation is important, and is also strictly necessary in many process areas. KNF has experience in this fi eld and appreciates its importance – e.g. for products used in nuclear power plants or potentially explosive atmospheres. The scope of documentation is determined jointly.

Are you looking for a process pump that meets the requirements of your proce-dure, your operating conditions and the properties of your media? We can provide considered, accurate solutions that comply with your instructions.

OUR PUMPS START WITH YOUR SPEC.UNCONTAMINATED TRANSFER, COMPRESSION AND EVACUATION.

Reliable and safe where it matters most.From sample gas pumps for analyzing process gases to emissions monitoring, the transfer of highly explosive media and the recovery of valuable gases, KNF’s solutions are used wherever it is crucial for processing media to be handled with special care. When it comes to implement-ing KNF diaphragm pumps that are tailored precisely to your process and operating conditions, your specifi cations set the benchmark right down to the smallest detail.

Experience and expertise that defi ne new standards. KNF develops and produces pioneering pump technology for use in demanding applications across a wide range of industries. As a global technology leader in diaphragm pumps and systems for moving liquids and gases, KNF supports customers by drawing on more than 60 years of knowledge and expertise.

Long-standing tradition of ingenious engineering. This is evident through development milestones, such as corrosion-resistant diaphragm pumps for chemical and process engineering, the temperature-resistant and heated pump head for hot gases of up to 240 °C and the double diaphragm pump for transferring hazardous and valuable gases.

All-round expertise in meeting complex requirements. From fulfi lling specifi c demands imposed by operating conditions to complying with technical procedural guide-lines and documentation requirements, KNF’s experts take everything into account, offering carefully consid-ered advice and completely adapting their solutions to client specifi cations.
