BUEHLER取样气泵P2.X ATEX系列产品介绍
即使在化学工业、石油化学或生物化学的爆炸性系统中，气体分析也是安全运行的关键。这些领域使用的许多分析过程需要样品气体的提取和特殊调节。
采样气体泵将采样气体从采样点输送到调节系统。在这些特殊设计的泵的主要项目是聚四氟乙烯单件套管。
结合泵头，也是单件的，这种解决方案提供了高抵抗特别具有侵略性的样品气体。转动泵头可以输送含有冷凝油的气体没有问题。
根据需求，有几种不同的型号都有不同的驱动器。这些版本允许安装一个联轴器法兰，将泵头安装在加热的壳体内，远离电机，而电机仍保持在壳体外。
该系列可用于各种EX危险和分类区，流量高达700L/h。
简单，坚固的设置
易于更换阀门
单件波纹管
用于腐蚀性样品气体
用凝析油输送样品气体
寿命长
可选可调旁通阀
聚四氟乙烯和VA泵体的旁通阀

带安装支架
ATEX版本类别2
Even in explosive systems in the chemical industry, petrochemistry or biochemistry, gas analysis is key for safe operation. Many of the analysis processes used in these fields require extracting and special conditioning of the sample gas.
Sample gas pumps convey the sample gas from the sampling point to the conditioning system. The main item in these specially designed pumps is the PTFE single-piece bellow.
Combined with the pump head, also single-piece, this solution provides high resistance against particularly aggressive sample gas. Turning the pump head allows gas with condensate to be conveyed without a problem.
There are several different models with separate drive, depending on the requirements. These versions allow the installation of a coupling flange to install the pump heads inside heated housings away from the motor whilst the motor remains outside the housing.
The series are available for various EX hazard and classification zones with flow rates up to 700 L/h.
Easy, sturdy set-up
Easy to replace valves
