Pumping Water in the Arctic!

As a small background to the project I am working on: I am currently doing my Masters of Architecture in Copenhagen, and we are designing devices to bring on our expedition to the North Pole, and I am harnessing salt water to pump through salt water batteries. My question is then: What kind of pump do I need to pump water up 2 meters? I don't need much water coming up at once, just needs to be constant. I am also looking for the most energy efficient way of doing this, any know of something? Any help is much appreciated! :) Thanks, AD

water pump idea

I hypothesise that when is heat applied to a suitable sealed vessel, filled with water, and having a pipe into the base of the container below the water level, that when the water gets hot enough, it will exit the pipe under pressure. if anyone has any input or had experiance with this kind of a thing or knows of a device which works in the same or similar manner, i would like to hear from you.  i though it could be a way of moving water with no moving parts or access to electricity, motors etc. thank Kim.C.S.B

Bike pump problem?

I was using my bike pump today to fill a pneumatic launcher, and finally I just got fed up with the leaking around the pump base. On every stroke, the first 3/4 of air would be leaked out of the base, and it would only compress the remaining 1/4 of air remaining, and that would only compress if you pushed down very hard, and quickly, otherwise it all leaked out. And no matter what pressure the launcher was pressureized to, the pump handle/piston would slide down slowly, getting pushed down under it's own weight, meaning that there was almost no resistance to it. I think the leak is occuring where the tube meets the pump base, and you can feel air rush out with your legs as you pump. I'm pretty sure there is a one way valve in the gauge portion of the pump, which connects to the base with a hose,  and the filling hose is coming out of it, which is allowing me to compress at least a little air before the rest leaks out. I disassembled  the pump, starting with the base. Turns out, the leak was from an oring on the tube which was not tightened down enough by a screw on ring around the base of the tube. Put it back together, and voila, pushing my finger against the schrader valve connector and pushing down on the pump handle created pressure against my finger and no leaking. As soon as I hooked it up to my launcher, i realized something was up, I could pump down once, but the pump handle just got pushed upwards as soon as i let go. This is what I can't figure out how to fix. It seems the one way valve in the gauge portion is locked in the open position. Anybody know how to fix this? EDIT: Okay I took pictures of the pieces. I now cannot figure out if the valve is in the base, or the gauge portion, so i have included pics of both. Hopefully someone can help me figure this out. EDIT 2: Turns out the valve is in the base, and the ball just fell out when i first disassembled it, i have now found the ball and it is working fine.

Vacuum pump voltage?

Today I was dumpster diving and i found an old vacuum so i decided to take the pump out but i made the mistake of not checking what voltage the vacuum runs on, because it also had a spinning component at the mouth of the vacuum. I think the pump works fine because i noticed that tube connecting the mouth of the vacuum and the pump was broke. Is there anyway to find out what voltage it runs on? would standard 120 be ok?The markings on it say 81 b-9 ECP 6500-240 HPU+ 60hz HD10 120 vac 07:07 does that mean it will work off a standard 120 outlet?update: What I am going to do with this motor has been decided. I will be attaching it to the back wheel of my bike with a car battery, i will install some type of switch on the handlebar or add something like a dimmer switch, this would allow me to have the motor on if i want, and i can adjust the speed. Please help fine tune this idea.

Advice on A centrifugal pump.

Hello, I recently was given a pet from a friend and after doing some research on what the little guy needs I came to the understanding that the current enclosure he is in is inadequate for his needs. Therefore, I wanted to save up some cash to get him the right size tank set up that I know he deserves. In the meantime though, I have plenty of things laying around the house that I feel could render him a more comfortable habitat till that investment goes through. After more research on the matter, I came to find that for most household aquariums, the bulk of the work falls on your filtration system. That being said, I wanted to go for a Wet / Dry Sump Filter setup as it would be  the most easiest system to setup at home with the various resources laying about. Unfortunately while gravity will be doing the work of siphoning the water from the tank down to the Wet / Dry Filter Media, it will not be moving it back up to the tank. For that I concluded there was no escaping the need of a pump in some shape or form to move that cleaner water back into the tank. From what I read the pump will pretty much determine how big I can make his tank.  So this brings me to my current dilemma. Presented with various motors around the house, I went for the biggest I could find (* excluding the water pumps in our cars mind you). That so happen to be a 1.25 HP Wet & Dry Shop vac that was collecting dust in the garage. I confirmed the motor is working and already came with the impeller attached to it. I was hoping to see if you fine folks could share some wisdom on how I can: 1.) Make it Waterproof. 2.) Adhere the right type of casing around the Impeller and Motor so as to benefit from the  Bernoulli's principle and get the most water moving through my system.  3.) I intend to have this setup not 15~20 feet from where I sleep, this motor is LOUD. I was reading online about creating a sound damping box for it and was wondering what suggestions you guys might have for that? I keep fearing there won't be enough ventilation and it will over heat. ....anything else you would like to throw in. TL;DR :

Circulating pump with thermostat

I have a 1550 gallon water holding tank and plumbing in an outshed in Fairbanks, Alaska. The pump and pressure tank are also in the outshed heated with an electric heater. To save energy I'm thinking to install a circulating pump inside the tank that circulates through the plumbing inside the outshed to keep it from freezing but not necessarily to the portion of water pipe going under ground to the crawlspace of the house. It should also have a thermostat to start heating when the temp of the water gets to 32 degrees or so. Is there any such thing and if so, how would it be installed? Thanks!

Air Compressor/Vacuum Pump

I have a theory: You have your supply of compressed air. You connect that by hose to one branch of a y-connector. The other branch is connected to a hose that goes into some sort of fluid that you want to move from one vessel to another. The trunk of the y is your exhaust (in theory). So now I give, say, 15 psi out of my air supply and that shoud drag my fluid out of its vessel through the y connector to the destination of my choosing. Would that work?

variable output dc water pump for a wind generator

I'm interested in figuring out how to direct the energy produced by a wind turbine into a water pump. My goal is to pump water from a river to the top of a hill into a pond. then slowly release it through a variable water turbine so that the pond serves as a battery. i've seen pumps that work with the power take off(PTO) of a tractor that could be retrofitted if i had the right dc motor. i need to figure out what motor might work and what type of contolling i would need. also would it be better to use several smaller units that engage one at a time as the power input increases to keep the pumps closer to thier ideal operating range? The (PTO)water pump i saw operates between 17-23 hp or 20kw or less, which is perfect because the turbine is 20kw. the other thing is what if the pump operation starts at 17hp(?) then most of the power would need to be directed somewhere when producing less. maybe a series of different sized pumps and a controller to determine which pump(s) to engage to get the most water pumped.
