A pump is a device used to move fluids, such as gases, liquids or slurries. A pump displaces a volume by physical or mechanical action. One common misconception about pumps is the thought that they create pressure. Pumps alone do not create pressure; they only displace fluid, causing a flow. Adding resistance to flow causes pressure. Pumps fall into two major groups: positive displacement pumps and rotodynamic pumps. Their names describe the method for moving a fluid. Positive displacement pumpsA lobe pump Mechanism of a scroll pumpA positive displacement pump causes a fluid to move by trapping a fixed amount of it then forcing (displacing) that trapped volume into the discharge pipe. A positive displacement pump can be further classified according to the mechanism used to move the fluid:

Q. or are there small pumps available that i can attach to a home made garden windmill. i want to use it for our garden pond as a water feature instead of using an electric pump. Asked by stanmysta - Sat Apr 19 19:16:51 2008 - - 1 Answers - 0 Comments A. There is someone in the Gladstone QLD area that make and sell working model windmills, they use a manual diaframe fuel pump operated by a crank, they look good. Sorry I don't have a contact number, as I saw them at a market. Cheers Answered by Lav farmer - Sat Apr 19 20:27:21 2008 How can I prevent my leather pumps from getting a crease in the toe? Q. I just bought a pair of really nice leather pointy toe pumps. However, I'm afraid to wear them because I don't want to get them messed up. I owned a similar pair (same brand, basically the same style) and they ended up getting a crease that was kind of raised right before the point of the toe and it looked awful. After one wear of these new shoes, I can tell the same thing is going to happen. Is there anything I can do to prevent it? Asked by jm4 - Wed Apr 11 12:29:07 2007 - - 6 Answers - 0 Comments A. You can fill the 'extra' between your toes and the end of the shoe, with tissue. (your foot isn't all the way up there anyway) and make sure when you get home you put your new babies on a shoe tree :) Answered by mochajavalatte25 - Wed Apr 11 12:33:15 2007 What's the best way to get gum off of leather pumps?
Q. I somehow stepped in gum the other night and managed to get it all over the side of my red leather pumps. Any suggestions on how to get it off? Thanks in advance... Asked by justhejumbles - Thu Jul 19 19:54:21 2007 - - 5 Answers - 0 Comments A. I would try freezing it off. That seems to be the easiest way to get gum off of anything. There's also this stuff out there, it's called "goo-gone" and it gets gum off of anything very easily. Hope I helped!
