KNF GAS AND LIQUID PUMPS

FOR DEPENDABLE RESULTS

Precision is the central requirement of instrumental analysis. Valid measurement results are needed for important decisions, when it comes to nothing less than the protection of people and the environment. In research, they are a prerequisite to drawing the right conclusions and advancing development. Dependable results can be achieved when components and functions interact precisely at each individual process step.

As the long-time solutions provider for well-known manufacturers of devices for routine and high-end analysis, we are familiar with this requirement. We bring our entire expertise to the table to deliver you a technically suitable pump, and additionally create advantages that provide you with added value. Along the way, we take into account the ever-growing market demand for faster analytics, ease of operations and cost efficiency. Together we will achieve the optimum!

Competence creates trust KNF impresses with outstanding engineering know-how. Thanks to our modular system we are able to adapt our many series models to specific requirements quickly and cost-effectively, thereby implementing your specifica-tions exactly. You can rely on this flexibility and quality of support from KNF for large as well as small lot sizes.

HIGH-PERFORMANCE AND COST-EFFICIENT

INTELLIGENT SOLUTIONSKNF gas and liquid pumps offer a range of advantages for use in analytical systems. One key asset is the membrane technology itself. This allows completely oil-free operation. Samples are not contaminated and oil changes are not necessary. The laboratory environment remains free of oil vapors for the entire service life of the analytical system. And the pumps are maintenance free.

Compelling advantages – engineered by KNFChemical resistance is an essential feature for instru-mental analysis. To make this possible, we offer a wide range of material combinations for the pump parts in contact with media – even for highly aggressive liquids and gases. We are constantly reducing the size of the pumps while at the same time improving their perfor-mance. KNF pumps for mobile analyzers and hand-held devices weigh just eleven grams. Via a manifold, our gas and liquid pumps can be integrated into any analytical system with a minimum of interfaces. They run quietly and smoothly, enabling a focused working atmosphere in the laboratory. And KNF pumps are known for their outstanding flexibility. Our modular system offers multiple options for every pump component. So you’re guaranteed optimal technical design and the right price/benefit ratio.

CHEMICALLY RESISTANT, QUIET, COMPACT

KNF MODULAR SYSTEM

CUSTOM-FIT FROM STANDARD TO HIGH-END

Every application is different and some are one of a kind. Our modular system is designed to give you a high degree of flexibility, speed and reliability. You can be sure that every gas and liquid pump supplied by KNF will exactly meet your requirements, no matter how complex or unusual these might be.

Series models – the first step to customized pumpsKNF offers a range of up to 70 series models designed for handling gases and liquids. The performances of these are described in our data sheets.

The KNF modular system for creating customized pumpsBy selecting and combining a variety of options, ranging from the material used to make the pump components that come into contact with the media, to the drive and the mechanical elements such as the circuit points and connections, it is easy to tailor every series model to meet application-specific requirements. The configurations created by the KNF modular system are based on tried and tested individual components, meaning that developing customized pumps is quick and inexpensive.

Project pumps – precisely designed for the applicationWe support your development project by providing you with sample pumps quickly and easily. In consultation with you, our employees from the sales, engineering, and product management divisions determine the modifications to be made to the product’s standard technical parameters.

LOW HEAT EMISSIONSThe N 96 emits relati-vely little heat itself while being suited for use at ambient temperatures of up to 50 degrees Celsius.

DURABLE AND CHEMICALLY RESISTANTWith an EPDM membrane or a PTFE coated membrane and valves made of FKM or FFKM, the N 96 is chemically resistant and highly tolerant of vapor and condensate.

PRECISEWith a highly efficient brushless direct current motor and rotational speed control, the N 96 can dynamically meet the requirements of complex operating profiles.

HIGH-PERFORMINGThe N 96 can start up without discharge in the range of 2.5 bar rel. pressure / 100 mbar abs. vacuum. The flow rate is as high as 8.5 l/min.

N 96 DIAPHRAGM VACUUM PUMP AND COMPRESSOR

HIGH-PERFORMING

The N 96 is suited for gas sampling analysis and all other procedures requiring reliable and precise transfer of liquid or gaseous samples. Compact and high-performing, it can transfer even aggressive and/or corrosive media. Its robust design means it can be used with a broad spectrum of media at temperatures up to 70 degrees Celsius.

This makes it perfect for use in inst-rumental analysis. In this field, the N 96 can perform the typical tasks of gentle, precise preparation and transfer of samples for analysis as well as safe disposal of chemical liquid waste mixtures.

UNIQUE CHARACTERISTICSSelf-priming, safe to run dry and at the same time the very low pulsation level makes secondary measures to avoid pulsing superfluous.

HIGH-PERFORMINGInfinitely adjustable flow rate boasts a maximum of 1.3 l/min, with outstan-ding linearity bet-ween 10 and 100 percent of this value. Not only that, but it is capable of resis-ting a back pressure of up to 2 bar.

LOW PULSATIONFive horizontally arranged diaphragms ensure low pulsation on both the pressure and suction sides.

CHEMICAL RESISTANTWith a choice of EPDM, PTFE or FFKM diaphragms, the pump can be equipped for applications involving very aggressive media.

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 techno-logy.

These specifications make the pump series particularly suitable for use

in instrumental analysis. It is able to handle liquid samples for the prepa-ration and transfer them for analysis without contamination. It also sup-plies the system with the cleaning agents needed for the various cleaning cycles. Thanks to the KNF modular system, the FP 150 is avai-lable in a range of different versions.

FP 150 DIAPHRAGM LIQUID PUMP

MAINTENANCE-FREE WITH MINIMAL PULSATION AND SHEARING FORCE

POWERFULIt is reliable and maintenance-free with a flow rate up to 16 l/min, an ultimate vacuum of 200 mbar abs. and an opera-ting pressure of 2.5 bar rel.

VERSATILE USEThe NMP 850 HP offers a variety of connection options, opening up a multitude of possible analytical applica-tions for the users.

CHEMICAL RESTISTANTPump head made of resistant PPS, seals made of highly chemically resistant FFKM, FKM or EPDM, and an FKM, PTFE respectively EPDM diaphragm.

FITTED IN ANY POSITIONBoth the single-headed and the double-headed variant of the NMP 850 HP can be fitted in any position.

With a flow rate of up to 16 l/min, the micro diaphragm pump can be used for a multitude of instrumental analysis applications, for example the disposal of samples residues.

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

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

NMP 850 HP MICRO-DIAPHRAGM GAS SAMPLING PUMP

A VERSATILE MICRO DIAPHRAGM PUMP
