What you should know about water pumps in vacuum chaers

Jun 05, 2017· Water likes to stick to surfaces and reside there until it desorbes, only to stick to another surface. This is why the predominant gas load in a chaer at high vacuum pressure (which is approximately between 1×10 -3 and 5×10 -8 torr) is water vapor. As one pumps a chaer full of atmospheric gas, gases such as Ar, N2 and O2 are quickly removed.

Vacuum Pumps: Why use them & what do they do?

The vacuum pump can reverse every one of these problems by reducing, eliminating or even putting a negative pressure on the engine. The net result is better ring seal, less or no oil contamination, less oil leaks, cleaner oil, longer engine life and MORE HORSEPOWER. An added advantage is your engine builder can use lower friction ring packages

WHY USE A VENTURI VACUUM PUMP

In many appliions the venturi vacuum pump is superior to a mechanical pump. Here’s why: High reliability - since vacuum pumps have no moving parts, they are much more reliable than mechanical pumps. No heat is generated - because no moving parts are involved no heat is generated. The expanding air in the vacuum pump also keeps the system cool

Laboratory Aspirators: Water Aspirators vs Vacuum Pumps

Moderate use at this rate is equal to approximately 50,000 gallons of water per year, per aspirator. Vacuum pumps, on the other hand, completely avoid the issues associated with water usage, as no water is required to operate the pump. Importantly, any biohazardous material can be discarded of properly in a much safer manner.
