Pond pump size -- need to pump 12-15,000 gph with HIGH HEAD

I am in advanced stages of planning a water garder in orlando florida.unable to decide the pump as i am unsure of actual TDH -- i would have a 5000 gallon and a bog which needs to a pump to water from the bog to top of a aquascape biofall grande -- the challenge is the waterfall is 70-75 feet away and 7 to 8 feet high -- the land follows a natural decline allowing a beatiful strem from the fall to the pond but distance and height from the bog to fall is messing up the pump head --- can someone suggg a cost effective way to overcome this.??

    Its not uncommon for some pumps to over come 15 to 20 feet of lift...the issues have to due with balancing your target flows 12 to 15 k is a LOT of water. When I worked in Biotech we had pumps that could supply 100 K plus flows at 90 psi in 4" lines. Big pumps eat a lot of juice and are pricey...you can find something but its going to cost you both up front and in electricity.

  • I have not calculated your numbers but could you have a bottom bog or pool and half way up your creek build another pool? this would require 2 pumps, one to pump from lower pool to upper pool and another pump that pumps water from the upper pool to the top waterfall. This may help I have seen several built this way.

    Sorroundings idea would required 2 (big pumps) with the added expense of the second pool and the electric to run both pumps....Two big pumps in series would have to have the same big flow rates...but two pumps in parallel may be the better option...two 6 k pumps could provide the total 12 k needed...

    If you need pump experts, call Coastal Pond Supply (770) 496-5740 and ask for Bill Dowden (and tell him HI for me)

  • I would suggest contacting Jim at Pondtastic 407-601 POND he specializes in ponds and has many years experience. It is one thing to read the specifications of a pumps flow rate and head high abilities and another to know how that will look in your waterfall. They are on 441 in Orlando.

    Gaddis, I have a 2500 gallon pond and I also have a pond company I use anytime I change my mind as to what I want. I have received excellent service. In fact I do have a new project because I want pond cleaning to be much easier. I've had my pond for many years. If you want a phone # to call let me know.
