Reasons why diaphragm pumps in food inspection equipment contribute to ensuring food safety.

  • Product news

KNF diaphragm pumps play a crucial role in ensuring the quality and safety of food products such as dairy and wine. The Importance of Food Inspection Food inspection is essential for several reasons. It identifies contaminants that may be present in food and ensures that the food is safe for consumption. It also verifies the accuracy of nutritional labeling, which is very important for consumers who rely on this information to make dietary choices. Furthermore, food inspection supports regulatory compliance, helping manufacturers meet industry standards and avoid legal issues. For these reasons, the food industry relies on inspection equipment, such as analytical devices, to ensure that product quality standards are consistently met.

Diaphragm pumps support the future of dental treatment with lasers.

  • Product news

The KNF gas pump plays an important role in laser dental treatment. It is used to generate compressed air, which is mixed with water to produce a spray mist. This mist helps to cool the oral area during treatment. Both the NPK 09 and NPK 09.1.2 are essential to this process. These swing piston gas pumps are oil-free, have a high performance-to-size ratio, and are highly reliable. The flow rates are 15 l/min and 24 l/min respectively, with a maximum pressure of 7 bar (gauge pressure) for both pumps. Liquid diaphragm pumps also play an important role in laser dental treatment. Pumps like the FMM 20 are typically used to cool the laser with deionized water. The FMM 20 is designed for dry running, is self-priming, and is maintenance-free. Its maximum flow rate is 0.018 l/min, maximum pressure is 1 bar (gauge), and maximum suction height is 3 mH20.
