Small waterfall no idea what pump

[Joyy]

I have a small pond and want todo a waterfall eventually
Is this pump suitable? I’ll post pictures and if not what would you recommend?
I am planning to use a spillway for the waterfall I’ll post pic below

Looks like it might work.

Agreed it might work, depends how big that waterfall container, how much water it can handle pushing through it and how high you are trying to push the water.
1000liter pump isn’t pushing that much water, so it may not give you the look you want which I assume is a sheet of water cascading of the waterfall edge.

keep in mind if you get a bigger pump you can always add a T and valve so you can adjust the flow to the waterfall.

Awesome thank you ! I might just test it out

How many gallons are in your pond? Is it the same one you posted pics on in another thread?

I have about 75 gallons in my pond/falls and I use a TetraPond 1200 gallons per hour pump (link) and what looks like the same size waterfall box (8 inch spillway), and I split it between a fountain head in the lower pool and the falls with about a 20/80 split (20% water pressure to the fountain and 80% to the falls) using a T shaped plumbing fitting. For waterfalls, your pump should move at least 100 gallons per hour for every inch wide the waterfall is. If you have an 8" wide waterfall spillway, then you need a 800GPH minimum pump (that's 3028 liters per hour), but taking in rise and adding in a fountain and wanting good flow, I think my 1200GPH pump is just about right for that size waterfall box. My falls have about 3.5 feet (about a meter) of rise from the pump in the bottom of the pond to the waterfall box and I get a decent but not glorious waterfall flow from that size waterfall box. Let me math that out to liters for you... 1 US gallon = 3.78541 liters, so to get a pump the same strength as mine, you'd need a 4543 liter per hour pump. It's possible you do not have as much rise as I do, but I would not suggest going with a pump that moves less than 3000 liters per hour if you want any sort of decent flow from that waterfall box. Here are some links to help you figure out how small of a pump you can use:

For reference, here is my pond waterfall showing you how much flow I get from that waterfall box with my 1200GPH pump. Cutting the fountain off does not increase the waterfall volume perceptibly:

If you want links to all the stuff I'm using I can post them here. That pump you have there says it's 1200LPH, which is only 317GPH (if my math it correct, if not do correct me!), it will not work for a waterfall box that is more than 3 inches wide. Those are pumps like you would use for just a small fountain, not for a waterfall. I found a similar 300GPH pump on Amazon.com to find you a photo of what a 300GPH fountain pump in action like this looks like. It's just a drizzle:
