Containment You Can Trust: LeakTight Diaphragm Gas Pumps for Critical Applications
Gas containment is critical in many industrial and scientific applications. Even the smallest leak can lead to safety risks, product contamination, regulatory challenges, or financial loss when handling toxic, explosive, corrosive, or highly valuable gases. As processes become more advanced and purity requirements increase, reliable leaktight gas handling is more important than ever.
KNF leak-tight gas pumps combine proven diaphragm technology with advanced engineering to ensure safe, clean, and reliable gas transfer – even under the most challenging conditions. KNF works closely with customers to meet these demanding requirements.
When Leakage Is Not an Option
Applications like semiconductor manufacturing, gas purification, noble gas recovery, analytical instrumentation, hydrogen and fuel cell technologies, or environmental monitoring all depend on precise and secure gas handling. In these environments, contamination must be avoided, and hazardous media must be fully contained.
Diaphragm pump technology, by contrast, offers an inherently clean and safe solution – especially when specifically engineered for leaktight operation.
The Advantages of LeakTight Diaphragm Pump Technology
Diaphragm gas pumps separate the pumped medium completely from the drive mechanism, enabling oil and contaminationfree operation. KNF pumps also feature precisionmachined heads, optimized sealing, and carefully selected chemically resistant materials.
KNF leaktight diaphragm pumps can achieve leak rates down to 10⁻⁶ mbar l/s. This makes them suitable for handling aggressive, reactive, or ultrapure gases, as well as hazardous or expensive media. The KNF pump portfolio covers flow rates from 2.6 to 250 l/min, pressures up to 12 bar (rel.), and vacuum levels down to 0.5 mbar (abs.), offering flexibility for many different operating conditions.
- Key benefits include:
- Low leakage to prevent media loss and emissions
- Maximum purity through oilfree, gastight operation
- High chemical compatibility for demanding gases
- High reliability with low maintenance requirements
Safety Engineered into Every Detail
KNF offers additional protective features for applications with high safety demands. Pumps are available in explosionproof versions and can be equipped with a secondary safety diaphragm.
This optional diaphragm provides an extra level of containment, preventing media from escaping the pump in the event of primary diaphragm failure. This added protection is especially important when handling pyrophoric, toxic, or explosive gases, or when complying with .
More Than a Pump: A Trusted Engineering Partner
KNF places strong emphasis on close collaboration with customers. KNF engineers work together with system designers and operators to understand media properties, operating parameters, safety requirements, and regulatory constraints. Each leaktight pump is carefully configured and thoroughly tested before delivery. Depending on customer or regulatory requirements, this can include advanced testing methods such as helium leak testing to verify maximum reliability and containment.
