FAQ OverviewTechnology
Volumetric flow rate is the most common way to represent flow. But in some applications, like chemical processes, knowing the actual amount of gas molecules is needed. In these applications, it is much more useful to express the flow rate as mass flow. The KNF Mass Flow Calculator can help you convert your volumetric flow rate to mass flow rate by simply selecting a gas or gas mixture and entering the volumetric flow.
Learn MoreThe diaphragm is the heart of KNF pumps and plays a key role in the performance. Many different technical applications can benefit from the use of diaphragm technology. Amongst other advantages, it prevents media contamination and ensures excellent leak tightness for media transfer. Learn more about how the technology of our diaphragm pumps works.
Pump TechnologyDiaphragm pumps can be used for both gas and liquid, hence they are dry-running safe and self-priming. They also tend to be very long-lasting, because they don't have any moving seals which can wear out over time. This also helps to keep the transferred media clean, because the pumps don't require any lubricants and the risk of abrasion is minimal. Furthermore, the transferred media is handled very gently, as it is not exposed to high shear forces.
Pump TechnologyThe unique modular design of KNF solutions allows our engineers to assemble each pump from individual key components. We can customize the mechanics, the materials, and the motor to our customers’ requirements, allowing to select advantages such as high capacity, extended service life, high pressure, leak tightness, high chemical resistance, noise reduction, different port configurations, and much more.
