The Gas Sample Pump – Flexible, Powerful and Easy-to-Use

The gas sample pump to be flexible, powerful and easy-to-use. It also needs to be robust and resistant against aggressive, corrosive gases. At the same time, it should be light enough that users can comfortably operate it for long periods of time – especially in hazardous areas.

These requirements have led to a number of innovative designs that have made it possible to increase performance without negatively impacting size or safety. For example, the KNF reworked how the components involved in gas conduction interact and optimized the valve construction, which consists of valve plates and sealing rings. As a result, the pumps achieve significantly higher flow rates than previously and are capable of transporting liquids as well as gases.

To ensure a gastight seal, the tube must be expanded slightly at the end where it attaches to the pump tubing barbs. This can be done using a hair dryer or heat gun. Alternatively, the tip of a screwdriver can be inserted into the tube to dilate it. This makes it easier to fit the handle and then lock it into place.

The gas sampling pump is used to transport the sample gas directly from the sample point to the analyzer cabinet. It is a key component in the continuous extractive gas analysis systems that are used in a wide range of applications, such as emission measurement e.g. in waste incineration plants or in power stations as well as process measurement e.g. in chemical, steel, glass and petrochemical industries. The diaphragm sample gas pump N86 KT21E is suitable for continuous extraction and pumping applications, for example with bypass valves. It is also ideal for transporting moist sample gas. It is Atex and IECEx Zone 2 rated, FM C-US approved, and can be powered by 115 or 230 V AC 50/60 Hz power supply.
