  • Towards the Single Pump Solution - Recent Development in High Speed Machines for Dry Vacuum Pumping (.pdf)
    The goal of a single _dry_ pump capable of reaching high vacuum and itself exhausting to atmospheric pressure has long existed in the vacuum field. The development of a single-shaft, high-speed pump EPX _second generation_ mechanism has gone some considerable way to achieving this goal. The pump
  • Vacuum and Pressure Handbook: Combined Systems, Appendix [Sample Problems, Glossary]
    Problem: A pressure source is used to agitate a plating tank of corrosive chemicals. Depth of liquid in the tank is 6 ft. A pipe with forty 1/32-in. diameter holes placed at bottom of tank will discharge air and promote agitation of the fluid. The pump must be oil-less so that no oil contamination
  • Selecting the Right Motor Technology for Miniature Pumps
    Miniature pumps are devices that utilize different technologies (diaphragm, gear, vane, peristaltic) to pump a fluid or create pressure or a vacuum. These pumps are typically less than 5" in height and draw < 100 Watts of power. Blood gas analyzers, gas samplers and oxygen concentrators are a few
  • Introduction to Peristaltic Pumps
    have the peristaltic pump. By mechanical simulation the tube walls are squeeezed together to form a seal as the roller moves along the tube. The previously compressed tube regains original form and sucks fluid/gas into the formed vacuum to create a self-priming function.
  • How Pumps Work
    or gas) is pushed along in front of it. Behind the rolling pin, the tube springs back into its original shape, which creates a vacuum; atmospheric pressure pushes the fluid in to fill the vacuum. As the rolling pin approaches line B-B, start a second rolling pin at A-A. This will allow the pump
  • Medical Device Link .
    Unlike piston pumps, miniature diaphragm pumps do not require lubricants in the pump 's stroking mechanism. On a similar note, rotary-vane pumps are prone to the vanes wearing and spewing debris in the flow path. By contrast, miniature diaphragm vacuum pumps and compressors provide an oil-free
