A vacuum cleaner (also hoover in colloquial British English) is a device that uses an air pump to create a partial vacuum to suck up dust and dirt, usually from floors.
Before I started doing the film and when I found out I was going to be doing it, I just decided to pump up on the whole cardio stuff. Just in terms of stamina. Parminder Nagra
Energy companies, such as Chevron and Shell, and oil producing countries, such as Kuwait and Venezuela, pump crude oil from their vast land holdings and sell it on the world market. Gary Miller
Even if gas prices fall, consumers will continue to be gouged at the pump the only thing that we can be sure rises faster that the price of gasoline is the skyrocketing profits of oil companies. Major R. Owens
Five years of Republicans' failed energy policies have resulted in Americans paying twice as much at the pump as they did in 2001, while big oil companies make triple the profits. Russ Carnahan
For far too long, America has been without a comprehensive energy plan, and today consumers are paying the price - literally - at the pump and in their heating bills. Chris Chocola
People really feel that, when they go to the gas pump now, that the oil cartel is holding them by the legs and tipping them upside down and shaking money out of their pockets. Ed Markey
Positive displacement rotary pumps are pumps that move fluid using the principles of rotation. The vacuum created by the rotation of the pump captures and draws in the liquid.
The low pulsation rate and gentle performance of this Roots-type positive displacement pump is achieved due to a combination of its two 90° helical twisted rotors, and a triangular shaped sealing line configuration, both at the point of suction and at the point of discharge.
There was a moth in there, and it still had its wings crumpled up, and it was just starting to pump its wings up. Life continues in lots of places, and life is a magical thing. Laurel Clark
