Diaphragm Pumps

Miniature Diaphragm pumps are suited for applications ranging from portable battery powered devices, such as air sampling, to laboratory and medical instrumentation. Parker also offers a full line of miniature liquid diaphragm pumps. Liquids have higher fluidic resistance compared to gas or air due to being incompressible and of a much higher viscosities, so the internal fluidic resistance of a liquid diaphragm pump is a driving factor in its performance capabilities. Our miniature liquid diaphragm pumps have an excellent track record in medical, scientific instruments and harsh industrial applications. The unique diaphragm design, combined with our close attention to bearing and motor design details, provides customers with substantial cost savings and reduced field service time.
