Pump accessories

KNF offers a wide range of customizable diaphragm pumps for gases and liquids. By using accessories, users can further customize these pumps to meet specific needs. KNF's modular system provides a variety of customization options, allowing the pumps to be tailored for specific applications. However, the fine-tuning does not end once the pump is manufactured. By adding various accessories to the pump, it is also possible to achieve more specific and detailed customization after the pump has been produced. Reasons to add pump accessories Accessories are a cost-effective way to specially adjust the pump for the application. In situations where custom engineering is not practical or feasible, they can be added to the pump relatively quickly and efficiently. Accessories help the pump achieve the desired results, and in many cases, the negative impact is minimal or nonexistent.

Silencer for micro pumps

- Silencer for bamboo joint (directly attached to pump) - Silencer with tube - Noise-canceling tube
