120v Water Pump Question

I'm wanting to pump water from my pool to the roof of my shop. About 15' change in height and 200' of 1" pipe. Can anyone suggest what size of pump I should get?

 

Not a very big one, 200’ of 1” pipe only holds about 6.75 gallons of water when full. Your gradient is 0.75 (slope=rise/run) which is small too. I’m no pump expert but you’re looking as a pretty small pump, depending on how quickly you need it from point A to point B.

 

Maybe the resident h2o expert can chime in.

1/10 HP. 1/2 HP? Just wondering about how much jam I'll need to have this work and not be burning out pumps. It would only run for 2 min every 30.

 

Using larger than 1" pipe I would extend the pools discharge line to where I need the water to go, and then use the 'backwash to drain' feature built into the existing pool filtration pump to move the water. The less restriction, the better.

 

Thanks for the fast response. I tried using a filtration pump, but it died. I have a simple above ground pool. So I'm not sure about a backwash to drain feature.

 

OP, is this for a water slide?

 

A tough guy slide...... Asphalt shingle slide, 4' drop into 4' of water. Will film and post if I man up and try it

 

It’s not so much about hp as much as you need a pump that can overcome the head pressure. Centrifugal pumps are heavily influenced by head pressure as the head increases the pump will eventually stop pumping known as shutoff head.

You will need a pump that can pump the head plus the additional head caused by the friction of the water flowing through the pipe. When looking at pumps they usually tell you flow rates at various heads. The slope doesn’t matter vertical elevation is vertical elevation. The rated flow rate usually advertised is the max flow at little to no head pressure it can be somewhat misleading.

long story short. Find a pump that gives the desired flow rate for the head it has to overcome. If the flow is below the minimum necessary flow rate the pump can burn out because the water flowing through it cools the pump and carries away the heat.

if you happen to have a positive displacement pump than that’s a different story.

 

Thanks for the input!!!!
