User Question- Best Pump for Lifting Lake Water to Camp

The elevation is 62 ft which is roughly 20 m which is roughly 2 bar of pressure to be achieved to lift the water. Most pumps should be able to do this.

Now not being able to submerse the pump means you need a suction hose. Place the pump close to the water line and insert suction hose in lake. Prime pump with water and pump as required.

Pump selection will have to be done by flowrate required and/or by money available.

"Interesting User comment looking for . . ." Is my English bad or is this a User name? Oh Paddy my Flanigan had a comment from an interested/interesting user?

Is this pump request for Paddy O'Flanigan, or a customer of Paddy O"Flanagin's??

Based on the last few requests from Paddy, I'm getting the impression that Paddy is a paid consultant, taping our brains.

What's the story, Paddy?

A suitable pump/check valve would probably do it. The calculations are readily available on the web at most pump suppliers web sites.

Color me skeptical..............................

Sorry, nothing fishy here. I'm just a GlobalSpec Joe that watches the user comments that come in and responds as appropriate. Once in a while I'll get a question that I think would make a good post on CR4 because-

1. The user (GlobalSpec user) needs to flesh out his requirements before approaching a manufacturer, like this one.
2. I really don't know how to help and the CR4 community is a good knowledge well to dip into.
3. Just a fun or interesting question that might liven discussion or gain traction for CR4.

Regardless, I always e-mail the user that I have posted her or his question on the board if they want to follow it.

So, "User Question" is simply a way of using CR4 to help field a question that has come in on the GlobalSpec site.

Cheers.

Sorry for the suspicious bent of my post.

Great service you're providing, and I'm confident that the usual suspects will agree.

We have a 50' deep well back on the farm, with a foot valve at the end of the 40' of down tube. It worked without fail for at least 25 years. Pump's a no-brainer.

So do we. However, we use a self priming centrifugal pump since the high ambient temperature causes vapour lock at times.

My thought would be to dig a new sump for the existing submersible pump located a short distance away from the lake, and bury a horizontal 6" PVC pipe connecting the lake to keep the sump filled with water.

You can use a convertible jet pump, two pipe system to lift the water from the higher elevation.It pushes water down one pipe,thru a jet at the bottom,where it makes a u-turn with an eductor that pulls water from the source thru the bottom of the jet housing.Normally, one pipe is 1 1/2" and the other is 1 1/4",with the larger one being the return.You select your jet at the time of purchase, and you must know the desired flow rate and total negative head;the height of the pump above the water level at the suction source., as well as the desired pressure and flow needed.More information will be needed if you need a specific recommendation.

Be aware that all pumps will fail if trash is pumped into the impellers and jets, unless specifically designed to be a trash pump.

A good pre strainer and strainer is recommended on the inlet side.

A cheap pre filter can be made with a 5 gallon bucket,drilled with 1/4 inch holes,covered in fiberglass screen mesh.Remember, it takes about 16 1/4 inch holes to equal a 1 inch pipe, and the screen will create some negative head.More holes(50 or more) are better,and will give less restriction.

Insert your final strainer thru a hole in lid into the bucket which is submerged.

Good luck with your project.

.... You can also consider putting the pump on a floating platform, suck from the lake directly under the platform and use a short flexible hose to connect to the delivery pipework. Select the pump for the flow rate required at the 62' elevation.

If you want a delivery pressure of 50', then the pump should be rated for pumping your flow rate ( gallons per minute (or other units) ) at the 62+50 feet= 112 feet H

You should add friction losses etc ... take it Height= 120 for the Q (G/minute) ....

A bucket, you make getting water too easy everyone will show up.

Then the camp will turned into a town. And you will then be looking for a new place to camp.

I thought the idea was to leave civilization behind not bring it with you.

Great point OZZB. A bucket costs a whole lot less and requires no electricity. It is funny what some people's idea of camping is. I bet they have the internet as well. Some that can afford it confuse having a second home in the "woods" with "camping out".

There was likely an economical reason for selecting a submersible pump in the first place. To replace it with a jet pump will cause some issues and questions to ask a good pump supplier who specializes in pumps;

1. Know the total length of pipe required, vertical lift is 62 feet but we do not the total horizontal component.

2. What discharge head are you looking for or rather how much psi do you want at the tap. 60 psi (140 feet) is common.

3. Do you want to locate the pump in a pump house near the shoreline or do you want the pump located at the top of the hill in your house (?) or some other structure?

4. Your selection of 3 will dictate whether you need a two line jet or a shallow single line jet pump.

5. If $600 is your total budget, you may want to visit Delmer's post regarding putting in a shallow dug well near the shore line with a good gravel pack. That way you can still use your existing submersible but the pump will not be in the lake (a little safer for swimming). Not sure of your situation but that seems the best option.

6. Here is a tutorial on pumping systems. I am sure there are others on the web.

"There was likely an economical reason for selecting a submersible pump in the first place"

Where did this imaginary submersible pump come from?

OOPS!

I missed that last line about the existing sub.

I take it all back.

From OP:

" There is an existing submersible pump and system in place 1 1/4 inch PVC sch 80 pipe 220 volt control with small tank & bladder."

I assume it is in working order.

Dear Mr.Paddy O'Flanigan

Jet Air Pump will be the best option.

Centrifugal Pump - above Water Level - has got SUCTION LIFT LIMITATIONS - normally you cannot go beyond 26 Feet or 7.92 Metres, on account of VAPOUR LOCK PROBLEM.

DHAYANANDHAN.S

Just as many other contributors have recommended, I would use a self priming centrifugal pump. Mount it as close to the surface of the water as possible to reduce suction limitations. If possible, use a rigid pipe for the intake instead of a flexible hose to reduce suctioning in of the hose. Place the end of the intake pipe at the level within the water source that you want it to be at. Use a foot check valve with a screen at the lower end of the pipe (submerged). Pipe the outlet of the pump up to the place you need the water. If you want, add a pressure switch to turn it on/off and a bladder pressure tank to hold water, reduce start/stops and water hammer.

Make sure that the pressure curve of the pump will exceeded the static pressure required to reach the desired level. This difference, with the capacity at that level is the volume output of the system. A foot check valve will prevent water from coming back down and syphoning back into the lake. The screen on it will keep scum, small rocks, large sand, fish, larger insects and most all creepy crawling things out of the water.

Good Luck, Old Salt
