20KD Series

The 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.

Use of high strength glass filled PPS plastics ensure a robust construction with a high degree of air-tightness throughout the performance and environmental operating range.  

› Flow rate to 800 ml/min
› Extremely compact with a 12 mm body
› Flexibility of series, parallel or independent head configurations
› Low Flow option
› Stable flow valve technology
› Choice of iron core and coreless motors

The flat design also facilitates 'twin' mounting offering the flexibility of 4 independent gas channels within a 24mm width.  

This series is also available in a compact single head configuration (20K).

Flow control is available in combination with PWM Flow Controller.

Coreless Motor - LF twin

With 2 x 20KD mounted side-by-side a 4 headed pump assembly offers extreme versatility in a width of just 24 mm:

› 4 independent gas channels
› multiple series / parallel configuration options (example: 2 heads parallel + series + series to minimise evacuation time)
› vacuum to 95%
› extended life and mimimised sound and vibration by sharing the load on 2 slower running pumps
