N 96 — diaphragm vacuum pump and compressor: High performance for medical device technology

The N 96 is suited for all procedures requiring reliable or precise transfer of liquid or gaseous media. Compact and high-performing, it can transfer even aggressive or corrosive gases and liquid-gas mixtures. Its robust design means it can be used with a broad spectrum of media at temperatures up to 70 degrees Celsius.  
With an EPDM membrane or a PTFE coated membrane, the N 96 is chemically resistant and highly tolerant of vapor and condensate. This makes it perfectly suited for the typical task of gentle, precise preparation and transfer of samples for analysis. The N 96 is also ideal for safely aspirating mixed liquid chemical waste.

 

With a highly efficient brushless direct current motor and rotational speed control, the diaphragm pump can dynamically meet the requirements of complex operating profiles. The N 96 emits relatively little heat itself while being suited for use at ambient temperatures of up to 50 degrees Celsius. The pump can start up without discharge in the range of 2.5 bar relative pressure or 100 mbar abs vacuum. The flow rate is as high as 8.5 l/min.

NMP 850 HP - Micro Diaphragm Gas Sampling Pump

The NMP 850 HP micro gas transfer pump is available with one or two heads. It is reliable and maintenance-free, with a 200 mbar absolute ultimate vacuum and an operating pressure of 2.5 bar relative.
With a flow rate of up to 16 l/min, the micro diaphragm gas sampling pump can be used for a multitude of different applications, for example the disposal of sample residues. The analysis of biological samples generates mixtures of liquid chemical waste, which is why a robust and reliable pump is needed. KNF’s development team met this need by coming up with a pump head made of resistant PPS, seals made of highly chemically resistant FFKM, FKM or EPDM, and a diaphragm in FKM, PTFE or EPDM.

 

The single-headed version of the NMP 850 HP processes samples and transfers them to be analyzed, either as a liquid in pressure-over-liquid form or as a gas.

 

The double-headed version of the micro diaphragm gas sampling pump can be used for degassing liquid samples. Dissolved gases in the samples may affect analytical accuracy, reproducibility and performance. When integrated into analytical systems, the specific vacuum can be adjusted via speed-controlled motors, ensuring accurate results.

 

Both the single-headed and the double-headed variant of the compact, high-performance NMP 850 HP can be fitted in any position.

FP 150 New Diaphragm Liquid Pump with Unique Characteristics for Medical Device Technology

If you are looking for a maintenance-free diaphragm pump with minimal pulsation and shearing force, look no further than KNF.
The FP 150 is the company’s second pump series based on a 5-membrane design that combines the advantages of diaphragm pump technology with the benefits of gear pump technology. The FP 150 is self-priming and safe to run dry, and at the same time the very low pulsation level makes secondary measures to avoid pulsing superfluous. Depending on the system set-up and speed, the values at the pump outflow at nominal flow rate are below 150 mbar.

 

Another winning feature of the new diaphragm liquid pump is the infinitely adjustable flow rate. The FP 150 boasts a maximum flow rate of 1.5 l/min, with outstanding linearity between 10% and 100% of this value. Not only that, but it runs smoothly and is capable of resisting a back pressure of up to 2 bar.

 

These specifications make the pump series particularly suitable for use in small cooling circuits such as X-ray machines or lithotripsy devices. The quiet and maintenance-free pump is ideal for applications carried out in close proximity to patients. Thanks to the KNF modular system, the FP 150 is available in a range of different versions.
