Miniature Diaphragm Pumps for Air and Gas

Diaphragm pumps are used in applications requiring a non-return airtight flow path and self-priming characteristics. From inlet to outlet the air or gas path is sealed from the outside world. This is ideal for applications where no contamination or dilution can be tolerated or the media is toxic. A diaphragm pump is equally ideal for pressure and vacuum applications. A miniature diaphragm pump is classified as having a flow of 5 l/m or less and will have a width of 20mm or less. The smallest Boxer pump is the new 20K with a body width of just 12mm.

... application parameters

Above this flow range they are classified as a diaphragm pump. Miniature diaphragm pumps are used, as an example, in mobile battery powered gas detection or dust analysers. Size and efficiency is critical to ensure a compact instrument with long battery life since often the miniature diaphragm pump is the largest and highest power consuming component in the instrument. Above 5 l/m a diaphragm pump is often used in larger devices which includes medical and environmental instrumentation. The Boxer range covers a maximum flow of 62 l/m with 7KQ. Diaphragm pumps in this upper end range are used for industrial pressure and vacuum generation in automation / pick and place systems. Importantly a wide range of DC and BLDC motors and accessories fully support the range. Most of Boxer diaphragm pumps will work equally well with a mixture of gas and liquid.
