N 87 TT.9E
Flow rate (at atm. pressure)
Robust and Durable
Equipped with the patented stress-optimized structured diaphragm, KNF N 87 TT.9E is a gas sampling pump featuring high pneumatic performance and long-term durability. Moreover, its special valves further ensure minimum resistance to flow.
Modulartiy in Design
Thanks to KNF Modular System, the parts used to transfer the gases can be made of materials with varying degrees of durability.
The pumps can be operated by either standard AC or ex-proof motors with various options on voltages and frequencies. Also see N 87 TT.9E Ex for models with ATEX/IECEx compliance.
