MICRO DIAPHRAGM GAS SAMPLINGPUMPS WITH HIGH PERFORMANCE

NMS010L

SECTION 22.30T

Concept

The Micro Diaphragm Gas SamplingPumps from KNF are based on asimple principal - an elastic dia-phragm, fixed on its edge, movesup and down its central point bymeans of an eccentric. In this waythe medium is transferred usingautomatic valves.

The new micro diaphragm pumpsNMS010 and NMS020 offersimproved pneumatic performancein conjunction with a smaller size.The new technology results in lowpulsation and minimum noise emis-sion.

Additional technical features includeefficient valve and sealing systems,as well as a precision boltingsystem on the pump heads.

Features

Uncontaminated flowNo contamination of the media dueto oil-free operation

Maintenance-free

Compact size

High pneumatic performancebecause of new oval diaphragm

Low aerodynamic lossby means of a new valve system

High level of gas tightnessthanks to the closed diaphragm sur-face and special sealing system.

Low pulsation

Low noise

Long product life

Ready for assembly

Can operate in any installed posi-tion

Areas of use

KNF Micro Diaphragm Pump NMS010 and NMS020 can beused frequently in the fields of analysis and medicine.

For instance as pumps for gas measurement, for example for sam-pling environmental conditions inthe workplace, or for exhaust gasand smoke analysis or built into ma-chines for measuring blood pres-sure.

As they are dc driven, these microdiaphragm pumps are suited foruse in portable and stand-aloneequipment.
