Description
Membrane contr. vac. pump N920KT.29.18G, 21 l/min, pump head Ryton®, membr. PTFE, with integrated gas ballast valve
For all applications that still require a large suction capacity at low pressure.For pumping and extracting air, gases and vapours, for sampling and evacuating containers or systems.
- The delivery rate can be adjusted by changing the speed using the potentiometer
- Ideal for aggressive and corrosive gases and vapours
- Very quiet and low vibration
- Diaphragm stabilisation system for high suction capacity in the lower vacuum range
- With integrated gas ballast valve for reducing condensate formation within the pump head
Application:for various processes and procedures, e.g. in laboratories, which need to be performed under vacuum conditions. Also usable in the semiconductor and pharmaceutical industries and in chemical and analysis technology.
