Hi all... New here and I can't think of anywhere else to go...

The manufacturer can't help me because, one they are closed... lol and two they had no Idea on what to tell me because they don't see it in a drawing...

I have a Flotec FP5732-01 (model #) booster pump. I took it apart the other day because it had "froze" up do to not being used for a year or so... Unfortunutly I forgot to take a picture or record any reference of the way it was suppose to go back together... So I have NO Idea how to make it work again.

On the plus side I got the motor running again and cleaned all the pump parts. This is a 10 stage booster pump used to make snow in the winter with and going to be used to pump down my gator tank this summer.

The manual to the pump can be found at this link...
On Page 10 you can see the exploded view of the pump. My problem is the "pump stack".. part number 7 on the repairs parts list under the diagram.

This is what I need help putting back together so it pumps right and fits back in the houseing.

There are 10 separete caseings, all with an impellar. It looks like the impellar pulls from the outside and pushes the water out of the center to the next stage. But this produce noise and minimal flow. IT was Incorrect. I figured I had just reversed the impellars and that was the cause.

I then figured that it could be sucking from the center and throwing it out the sides thus pushing it forward to the next stage. This might be the case but I just can be sure and I'm at a loss now as I don't understand how these work!!!

Thanks for any help you can offer,
Alex

The pump draws from the center and each impeller feeds to the center of the next impeller. The casings should direct the flow from the outside of one and into the center of the next impeller. The Flotec manual certainly doesn't help at all with the assembly of the stack. And you have to love the reassembly instructions to just follow the disassembly in reverse.

If the impellers flow from the center out then the intake of the impller has to face the inlet of the pump.

Ok, go that.... thks for helping me clear that part up. I'll take that info and try to work somthing out tomorrow with it. If I can't get it in the morning I'll post back w/ some pics.

Let you know how it goes..

Thanks,
Alex
 
The impellers should be backward curved so when arranged on the shaft the impellers should turn in that respective direction.

I would expect that each stage likely has a diffuser and impeller. While I've never seen the Flotec unit, I'd at least hazard a guess that it's similar to many other manufacturer's units. This link is to the parts list of the Goulds GB unit, it shows the individual diffuser/impeller/bowl, so it might help you:
