20KD SeriesThe 20KD series is a miniature diaphragm pump which, uniquely for this class of pump, offers the significant advantages of a double head design within a 12 mm width frame size. The double headed construction extends performance range to an impressive 75% vacuum and 1.5 bar pressure, reduces pulsation and offers slow running with the associated benefits of reduced sound and extended life. Typical examples include portable environmental gas analysis, medical monitoring, medical therapy and chemical agents / biohazard detection. Recognising that instrument miniaturisation often results in low performance requirements, the 20KD is additionally available in a 'Low Flow' configuration which maximises efficiency (hence also battery life) at the lower end flow range of this series. This is achieved through the use of optimised low speed coreless motors combined with a pump head specifically designed for low flow. These pumps are listed as below as 'Coreless LF'. Additionally stable flow valve technology ensures consistent operation at flows below 50 ml/m without influence from the pump's orientation.
