    the top one looks like a waterway but no name..

    The second one is the winner, it has a timer built in, bonus and I would get the 1hp 2 speed
    Pool: Intex 16x32 15000 gal, 2 speed 340042, Pentair CC320 Filter, CircuPool SJ45 Salt System, Intermatic PE653RC; Hot Tub: 650 Gal SWG Megachlor

    any reason for that instead of the 1.5 HP?

    I'm interested in the Doheny's pump as well. Any info on their pumps.
    24'x52" Above Ground Pool, Hayward Sand Filter, 1 HP Hayward PowerFlo Matrix Dual Speed pump, In-line Chlorine Feeder (only used when on vacation), AquaLuminator return light (customized with color changing LED light), all plumbing done with Schedule 40 PVC
    & 2004 Elite Spas Monterey Hot Tub (~400 gallons) with Controlomatic Technichlor SWG - Use Taylor K-2006 test kit with K-1766 addition and speed stir on both.

    curious as well still here. I need to replace some parts on my current pump as it leaks when its turned off, so I am thinking of getting this but curious if anyone else has experience.

    Re: Anyone know anything about this 2 Speed ABG Pump?

    I'm checking my calculating skills/understanding with regard to pump/filter match-ups. For the 1HP Doheney 2-speed pump mentioned in the original post, the web site link states this pump has a 75gpm flow. According to the table in the Hydraulics 101 Sticky under Filter Sizing, you would need a sand filter with a surface area of 5.59 sq-ft for that pump.
    Would that mean, he would need a sand filter of nearly 32" for the 1HP 2-speed Doheney pump in the link?
    Just looking for assistance to better understand the relationship between pump GPM, sand filter flow rate and filter size.

    Schnozz, you might want to read through this recent thread that I started, with very similar questions:

    Re: Anyone know anything about this 2 Speed ABG Pump?

    Singingpond.....thanks for the link. I've tried to find the GPM for the Pentair pump in the combination unit mentioned in your thread, PNSD0060DO2260, but have been unable to do so. The manufacturer mentions the GPM of the sand filter but not the 2-speed 1HP pump/motor. I have noticed what you have while shopping for a matched set. I've never seen a 2-speed 1HP pump matched with anything larger than a 22 or 23 inch sand filter. The Doheney pump, in the first post in this thread, is supposed to have 75GPM flow at high speed, necessitating a 32" sand filter according to the table. That would mean that the 2-speed 1HP Pentair matched set, PNSD0060DO2260, would have to have a flow rate of around 40 GPM to work with the matched sand filter, 22". Is there a bit of exaggerating the 75 GPM of the pump that started this thread? Can there be that great a difference in the GPM Flow of different 2-speed 1HP pumps?

    Re: Anyone know anything about this 2 Speed ABG Pump?

    I'm pretty sure the pump in the PNSD0060DO2260 is a Pentair Dynamo pump (I remember looking at it a couple of years ago). I haven't looked up the GPM rating lately (don't remember right now which size Dynamo). But, as you say, the filters in the matched sets are always smaller than the recommendation in the Hydraulics 101 table. [edited to add: In this particular Pentair matched set, I think flow rate and filter are closer to being matched than in many other packaged systems out there.]

    I believe there are significant flow differences between different pumps with the same apparent HP rating. Apparently there is no consistent meaning to the HP number (and there are terms thrown in such as 'up rated' and 'full rated' and 'service factor' which distort the HP numbers the manufacturers put on the units). If you take a look at the pump curve table [edited: I actually meant the "2 Speed Pump Flow Rates" table] for two-speed pumps (also near the top of the Hydraulics 101 thread - post #2 in the thread) you will see that flow rates vary quite a bit for supposedly the same HP.

    I wish I could trust some of the cheaper dual speed pumps out there (like this Doheny one, for example), but information on them seems hard to come by. On a different issue, I don't think I would buy this particular pump, simply because of the digital control stuff built into it -- just one more thing to fail, on a pump from an unknown manufacturer, is how that looks to me.

    Re: Anyone know anything about this 2 Speed ABG Pump?

    image.jpgSo, here's the Pump Curve for a 3/4HP Dynamo pump. (Not sure if it's exactly the same as a 2-speed on high, but I'm sure close enough for us amateurs) It appears, in actuality, that the 3/4 HP Pump can generate 70 GPM of flow with 10' of head. So the original 2-speed 1HP Doheney Pump that started the thread probably could generate 75 GPM of flow with an extremely low head, just like the Dynamo pump from Pentair in the graph. Depending on head loss it could be much lower. Maybe that's the reason the sand filters packaged with the 2-speed pumps seem smaller that the table in Hydraulics 101 mentions. On the graph above, can we assume the normal/actual GPM flow of these pumps is in the middle of the curve, maybe 35 or 40 GPM? Would that observation be on track? (Allowing for length of pvc plumbing/pvc elbows/ or other things that add head to a pump line) So when selecting a sand filter, you would not necessarily match this 3/4 HP Dynamo pump with a GPM of 70 and 10' head in the graph with a sand filter that has a GPM flow rate of 70 GPM to match it. Is that the reason the matched sets never have a filter as large as the table suggests? It appears, trusting the reputable manufacturers combinations may our best bet regardless of what the Hydraulics 101 table for filter sizing states, as we will never have enough motor/pump information at our finger tips to make the optimum selection for separate pieces and the manufacturers never seem to use the larger GPM filter the table suggests as optimal. We are most likely going to over size the pump and undersize the sand filter if we purchase each piece separately. I realize the matched sets are less expensive than buying a motor/pump/filter as individual pieces, but are the matched sets coming with an undersized sand filter?
    Maybe Ive missed something about Pump GPM in the sticky. I'll try again..

    It looks as though I may have hi-jacked this thread from Cain. If the moderators need to move it, separate it, or shut me down, please go ahead. If I need to move it or start a new thread, please let me know how and I'll take care of it....

    My my apologies to Cain as well....

    I will direct all my questions from this point on to this thread:
