Miniaturization Done by Precision Pumps

Jan 01 2000

Especially with portable gas analyzers, there is a trend towards miniaturization. These devices, particularly used in the field of smoke analysis and for protection of persons, are in many cases already smaller than cell phones.

A gas sample is sucked into the analyzer by means of a diaphragm or vane pump and is drawn over a sensor for analysis. Pump and battery pack, being the largest components, still require much space inside the device. So it's here where miniaturization must set in.

Schwarzer Precision (Germany) can do this successfully, since this company offers the smallest pumps of this type worldwide. Another important objective is to minimize the pumps' power demand to such an extent that the pertaining battery pack can be dimensioned as small as possible. This is done by finding the perfect combination of pump components matched to each other. Especially by the innovative HighResponse valve system, it was possible to reduce power requirements down to a level not attained so far. For applications requiring a very long service life, brushless longlife motors are also available, apart from double ballbearing servo motors.
