    4000 GPH Intex Pump with the 2650 GPH Sand Filter

    Can you use these two together but don't use the pump on the Sand Filter?

    Yes, you can use them together. Just bypass the other pump.

    Re: 4000 GPH Intex Pump with the 2650 GPH Sand Filter

    why would you want to run them together?

    Not sure, more waterflow? Maybe that's not the case?

    So you are thinking that the 4000 gph pump on the filter pump will have a higher flow than the pump on the sand filter?

    2650GPH vs 4000GPH yes but it looks to me like the horsepower on the 2650 is bigger than the 4000. I don't know enough about these pumps to make that big of an informed decision, that's why I asked.

    from what I have readt the 2650 gph has a 1 hp motor and the 4000 gph has a 1/4 hp motor. I would say that the 2650 is musch stronger. I have the 1600 ghp sand filter and it is stronger than the 4000 that came with my pool.

    I'm pretty sure the 4000 GPH is a 3/4 HP pump and the 2650 GPH sand filter is a shy under 1 HP.

    The 2650 is "rated" at .95hp. Not sure if its an actual or max rating.

    The 4000GPH will have a higher flow rate than the 2650GPH sand filter pump. **BUT** The 2650GPH is a much stronger pump and provide a more consistent flow than the 4000GPH. I had the 4000GPH and the water circulated great but the slightest clog in the line or the filter the water flow diminished rapidly. When I put the 2650GPH on my pool I did notice a slight less water flow but the pump was strong and continues to provide great water circulation even as the filter PSI goes up and the filter gets dirty. I would take the 2650GPH Sand Filter/Pump over any other pump that Intex makes. I can even add a 30' vacuum hose up to it and run my fountain at the same time it works great. The 4000GPH would not vacuum up nothing.
