Selecting pump for a watercourse

When you buy pond pumps online you often get information about maximum flow and maximum lift, but that’s not enough for making a proper selection.

What’s really important is the amount of water the pump delivers at the top of your watercourse. In order to find that out you need to know the amount of water the pump delivers at different heights, but this information is rarely specified.

Another thing that’s important to consider is that the hose used to deliver the water to your watercourse, due to hose-friction, decreases the amount of water the pump delivers. The hose-friction varies depending on hose-length, hose-dimension and flow-rate.

You see that it's not easy to compare different pump models. It takes a lot of time to make all necessary calculations - even for an expert. Pump-Demo let you do all this with just a few mouse-clicks.

Let Pump-Demo help you choose the pump that best suits your needs

My name is Fredrik Jacobsson and I'm a computer programmer with a history of water gardening for over 12 years. I have developed a Pump Selector (Pump-demo) that simplifys the pond pump selecting process.

I have heard pond pump retailers give the following advice to there customers: "don't choose a too small pump". What does this mean? It's impossible to know if you are not given information about the amount of water the pump will deliver at your home pond. From my point of view it's self-evident that the customer must be given this kind of information, at least if the retailer care about satisfied customers.

Most online retailers don't specify the amount of water the pumps delivers at different heights. Sometimes you cannot even find this information at the website of the manufactures.

The system I have developed - Pump-Demo - calculates the amount of water a pump will deliver based on head of water, hose dimension and hose length (hose friction considered). The system also recommends which hose-dimension you should use. You can search the database for pumps in a specific flow range and even compare the energy efficiency of the pumps. With Pump-Demo you can choose the pump that best suites your specific needs.
