    1/2 HP water pump ?

    I am looking for an 1/2 HP water pump to replace my current ome.
    I have been searching thru many websites - seems like Wave II and Sequence
    Primer are good pumps. Any brand recommendation is greatly appreciated.

    Aquatic Ecosystems is selling a Sweetwater brand pump. They seem to be as good as a Sequence. Baldor motor. Quiet. Good electrical efficiency. There is a low head line and a medium/high head line. I have never had a Wave, but everyone seems to like them.

    Do you run a bead filter or need high pressure?

    Dinh, I think it's the motor that counts and Baldor motors seem to the best. I am sure can get a good deal from Fancy Koi Outlet if you buy from them, they have the cheapest price in town in regards to Sequence and Wave II.

    Fancy Koi Outlet:
    WAVE II - 1/2 HP
    8400 GPH/ 5.31 ft. head / 600W
    MAX: 600W /
    [email protected] $485


    Sequence Primer - 1/2 HP
    7200PRM23
    1500-6600 gph,
    1/2 HP, 539 watts max $490.50

    The world sleeps as the chance to learn something new passes.

    A excellent place for pumps is also http://www.azponds.com/ Excellent prices and free shipping on most of their pumps, I bought a couple of the Sequence Self Priming series about 8 month ago and so far nothing but great results

    Before you look at price and brands how is it going to be set-up? Also how many GPH are you looking to get out of it?

    Better check twice before ordering some of the sequence come with Baldor motors some not. The non baldor motos are quite loud!

    Not only that Keokoi look at the flow chart on them. The primer at 12' of head only gives you about 5,000 gph. The Wave II at 12' of haed has 7,200 gph. The PreformancePro Artesian 1/2 hp at 12' of head you get about 7,380 gph.

    Another thing to think about is how much head pressure your going to have on the system The 1/2 hp Sequence primer shuts off at 23' of head. The Wave II 1/2 hp shuts off at 23' of head. The PreformancePro Artesian 1/2 hp shuts off at 25' of head. The PreformancePro Artesian and Sequence Primer are self priming pumps, and the Wave 1/2 hp is not.

    Keokoi was talking about loud motors. I have four PreformancePro Artesian pumps on my pond that are in a filter house. If I turn off the air pumps you would know that I have four pumps running.

    Just more to think about.

    Thanks much all for the information.

    Here are some background of my pond and the reason why I need to
    replace my current 1/4 Aqua Flow pump. My pond was original built
    for water garden purpose. It was built before I know anything about
    rasing Koi. It is a cement pond and it is about 5000 gallons. It does
    not have any bottom drains. The pump is connected to a 2" pipe thru
    the side of the pond, so it fed water directly to the pump and then to the
    bio-filter (1000 gallons bio-filter and it is designed as a waterfall) before
    returning back to the pond.

    There is no skimmer ;-(

    So, couple of weeks ago, I splitted the 2" pipe with the T connection to
    connect one to the Skimmer and one to the bottom. I have a control
    valve at the T section. If I set the valve 50/50 for skimmer and bottom.
    It works - but seems like it does not have much power to suck the dirty
    from the bottom. So I did some research and thru your info. Seems like
    I need a pumps with at least 1/2 HP for my setup now. Seems like Wave II
    1/1 HP with Baldor motor should be good for me.

    Thanks all again.
