What is the best pump for a 25 by 20 foot pond?

Question

We are in the process of building a very large pond (the liner for the pond itself is 25x20- estimated to be around 5000gph) is it possible to find a solar pump that will work with this size water feature??

Thanks!

Kathlyn.

Hi Kathlyn,

If your new pond is going to be in the 5000 gallon range then you would want to have a pump that can deliver around 2500 Gallons Per Hour. This will provide the best circulation and keeps the waters moving; adding a fountain will also help as will a waterfall to some extent. Solar pumps for waterfalls and solar pond pumps are usually able to pump only from 50 to 300 GPH unless you go to a larger pumping system.

Most solar pumps we install are not for driving water features or powering fountains put more for pumping from wells into cisterns or water storage tanks for use by livestock. The most rudimentary solar powered pumping system, even when a do it yourself attitude is attached, can be more time consuming and more expensive than considered.

A solar pump to deliver 2500 GPH, with a battery back-up for night and day operation, with a linear current booster, can cost several thousand dollars. DC air pumps and DC water pumps have been known to offer short life cycles often burning out within 6 months of continuous duty even the Thomas DC pumps so many of our clients end up using electric pumps and pond pumps.

There is more information on pumps and a pump we recommend that can deliver 2500 GPH on this webpage: http://www.thepondreport.com/pond-pumps.shtml Best of luck with your pond project and thanks for writing!
