This video shows you how to build the Peters Pump, a simple inexpensive direct-acting PVC hand pump suitable for shallow wells. You can see it working in these other videos I posted some time ago: http://youtu.be/MwGVH1ADMDs http://youtu.be/fUjlORcRA3k In this video it's attached to a small diesel pumping unit I built for irrigating with it: http://youtu.be/DzOrIq1bnqs You can see a 4" diameter version of it here: http://youtu.be/LgR3cE9MRBs Every place I've introduced this in the world I've had to adapt the design somewhat to use the parts available - this version is the one I build in the U.S. Other versions use thin wall pipe or black polyethylene pipe, or a different piston fitting that fits the pipe better, or a foot-valve that's held in place by forming the pipe with heat, or a foot-valve that uses a copper wire cage to hold the bottle cap in place. Sometimes the pipe ID varies between manufacturers and even between production lots, so you have to be careful. I've made several versions of the pump, and usually I have to spend a lot of time browsing the hardware stores to find parts that might work. So far I've always been able to build a working pump and show others how to do it, too. I hope you'll be able to do the same. [Safety note: please take care when heating PVC since it can give off toxic fumes. Have good ventilation, take measures to ensure you don't breathe the fumes. Don't burn the plastic, just heat it gently and only until it's soft enough to form. You can use boiling hot water to soften it also. Use common sense and stay safe.] I believe the piston valve made from a bicycle inner tube stretched over a perforated pipe is unique - I've not seen this used anywhere else. The main advantage is that it allows a lot of water to pass through it in spite of the small pipe diameter. It's also lasts for a very long time. Note that everything that goes into the water won't corrode - rubber, copper, plastic, stainless steel. This pump can easily last for many years of use because of that. The only parts that wear out are easily replaced using off-the-shelf or scrounged materials. The thumbnail photo is of a pump I installed in Bolivia in 2003. Notice the 2-liter bottle used as a sliding funnel to fill water jugs without spilling. During a subsequent drought the whole community got their water from this well since it was the only one that hadn't dried up. By the way, the little soda can stove in the video works great, and is based on the work of YouTubers 'Littlebitworks' and 'Tetkoba'. Look for "Groove Stove". It's made from one soda can in about 5 minutes, blossoms in about 3 seconds, and can cook for about 15-20 minutes. We're putting together a more complete printed instruction manual with photos and parts list for those who might want that. It will be available for a nominal fee to pay for printing and mailing. Email me at firstname.lastname@example.org. I work with an organization training folks in many technologies including this one. You can read about it at http://www.ibcd.net/en. If you have any questions feel free to ask. Thanks for watching!
Scotty Kilmer, mechanic for the last 46 years, shows how to find out if your car's fuel pump has gone bad. Some simple tests are all that's needed, and you don't want to guess with a new pump without testing, as some can cost over a thousand dollars to replace.

Video: How To Make A PVC Pump!
In this project you'll learn how to make a customizable PVC hand pump that will create vacuum suction, pump water, or compress air. http://www.thekingofrandom.com A pre-requisite to making the pump will be 2 homemade check valves. You can learn how to make these cheap PVC check valves here: http://www.youtube.com/watch?v=DG6own141z0 Music by Jason Shaw (TU-ForeverBelieve) http://www.audionautix.com My friend NightHawkInLight made another version of a vacuum pump. Check it out here: http://youtu.be/UkPLu6mgdWA Project inspired by: This is an original design, based off a picture I once found on a google image search. (I haven't been able to find the picture since) WARNING: Power tools, like a table saw, pose risks of serious injury. Adequate training and experience are required before operating. The results and claims of this pump are based solely on my personal experiences with the one demonstrated in the video. Individual results may vary. The pump is a simple design and not made, or claimed, to be used in any heavy duty operations, or relatively high pressures. Use of this content is at your own risk. I've wanted to build a PVC water pump for awhile, but the check valves were around $10.00 each. That seemed a little steep for a PVC build, so I made my own, which you can see in a different project. I was inspired on the pump piston and chamber by a picture I saw on a google image search by someone who used the 1-1/4" and 1" sizes of tubes, and he mentioned he cut the grooves for the O-rings on a table saw. That was a new idea to me and gave me the inspiration to put this together. I'm also planning to use this piston design in future projects that require pneumatic and hydraulic pistons. In my testing, the valves work great with air and water. I didn't have any gauges to test the strength of the vacuum so can't say how strong the vacuum would be, but it certainly does create one. While there are some special tools used to create this pump (table saw and forester bit), I believe with a little creativity the pump could be made just as effectively without them, making this a simple and duplicatable design.

They are extremely simple, with just two moving parts. The basic idea behind a ram pump is simple. The pump uses the momentum of a relatively large amount of moving water to pump a relatively small amount of water uphill. To use a ram pump, you must have a source of water situated above the pump. For example, you must have a pond on a hillside so that you can locate the pump below the pond. You run a pipe from the pond to the pump. The pump has a valve that allows water to flow through this pipe and build up speed. Once the water reaches its maximum speed, this valve slams shut. As it slams shut, the flowing water develops a great deal of pressure in the pump because of its inertia. The pressure forces open a second valve. High-pressure water flows through the second valve to the delivery pipe (which usually has an air chamber to allow the delivery pipe to capture as much high-pressure water as possible during the impulse). The pressure in the pump falls. The first valve re-opens to allow water to flow and build up momentum again. The second valve closes. The cycle repeats. The delivery pipe can rise some distance above both the pump and the source of the water. For example, if the pump is 10 feet below the pond, the delivery pipe might be up to 100 feet above the pump. You can see that the one big disadvantage of a ram pump is that it wastes a lot of water. Typically, only about 10% of the water it consumes actually makes it up the delivery pipe. The rest flows out of the pump as the water builds momentum. There is nothing magical happening in a ram pump. A different design that accomplishes the same thing might work like this: Water flows downhill from the pond and drives a water wheel. The water wheel is connected to a conventional shaft-drive pump (a reciprocating pump, a centrifugal pump, etc.) The pump moves water uphill. This design has more moving parts, but it accomplishes the same thing and has the advantage that it scales to any size very easily. The idea of using the energy of flowing water has been around for a long time!
This animated video is aimed at giving a logical explanation on working of centrifugal pumps. Importance of priming, cavitation and commonly used impeller types are illustrated in this video. They are the most preferred home water pumps. Mechanical design aspects of centrifugal pump such as water sealing arrangement and bearing housing are also well explained here.
