KNF Debut at Hydrogen Exhibition hy-fcell Stuttgart
Proven liquid and gas pumps as well as new models for the safe handling of hydrogen and hydrogen carriers
For two days – September 13 and 14 – international experts will meet on the congress stage and in the exhibition area of hy-fcell to exchange ideas. As the energy transition accelerates, hydrogen, hydrogen carriers and fuel cell technologies are playing an increasingly prominent role.
Matching its pace, KNF has been continuously expanding its product range of pumps for these future-oriented systems. KNF’s booth will showcase the latest low-pulsation pumps and a range of liquid and gas pumps, thousands of which have already been installed in devices for zero-emission power generation.
Pumps for electrolysis and the hydrogen value chain
Generation, storage, transport – many stages of the hydrogen value chain require pump technology. KNF offers airtight liquid pumps and gas pumps with a maximum flow rate of up to 250 l/min and a maximum pressure of up to 16 bar g. KNF’s oil-free pumps are available worldwide as ex-proof and non ex-proof versions.
The typical tasks of these durable diaphragm pumps include transferring, circulating and compressing gases, as well as dosing and circulating liquid media, such as electrolytes, condensates or alkaline solutions.
As a reliable and low-maintenance components for maintaining safety, KNF’s gas pumps work particularly well as gas sampling pumps in portable or stationary monitoring systems.
KNF’s high-performance and maintenance-free micro gas pumps are a sure fit for gas sampling pumps in portable devices for detecting hydrogen.
Airtight pumps as balance-of-plant components for fuel cells
Since the 2000s, the number of KNF pumps in fuel cell systems has been growing continuously. Research and industry use liquid pumps and gas pumps with low power consumption to make the overall system as efficient as possible.
Ex-proof and non ex-proof versions of KNF’s diaphragm pumps are recommended for tasks along the electrolysis and hydrogen value chain.
KNF gas pumps for recirculation are a case in point: Changing flow rates required by the respective operating mode can be precisely modelled using brushless motors that can be fully parameterized. The recirculation pumps are suitable for hydrogen with its high moisture content and changing density according to the pump’s operating point.
One further advantage is their compatibility with all types of hydrogen carriers. KNF’s pumps are able to accurately transfer and dose even extremely volatile carriers such as methanol, regardless of extended downtimes.
KNF’s liquid pumps and gas pumps can handle hydrogen and hydrogen carriers such as methanol, ammonia, natural gas and biogas for any type of fuel cells.
Thanks to their modular system, KNF pumps can be modified to meet the customer’s requirements. The required gas tightness, the motors and the material of the pump components that come into contact with the medium can all be customized.
