There's a lot more to draining a pool than meets the eye. Not only are there concerns over proper water disposal, but emptying a pool also puts the structure itself at risk. That's because many pool ...

High vacuum lines and valves should be designed in accordance with the nominal pumping speed of the high vacuum pump. Otherwise, there will be considerable losses in the effective pumping speed due to ...

In principle, industrial vacuum pumps are merely compressors run with the inlet attached to the vacuum system and the outlet open to exhaust. In smaller sizes, compressors and vacuum pumps are often ...

Single-stage and multi-stage vacuum pumps have been around for quite some time, but some designers and engineers remain unsure about when to use one versus the other. For example, which pump is best ...

Equipment: A pump and a tin quart sized can with a screw cap. What it does: The pump is attached to the can and is turned on to evacuate the can. The resulting vacuum crushes the can.

DARPA-funded researchers recently demonstrated the world’s smallest vacuum pumps. This breakthrough technology may create new national security applications for electronics and sensors that require a ...
