FAQ Overview


We provide answers to frequently asked questions regarding diaphragm pump technology.

The 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 Technology

Diaphragm 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.
