Filter too small & Pump too big??

[Hey_Dad]

Madwil - "when you say pump is hot, do you mean the pump housing, or the motor?" Answer: The metal part so the motor is what seems to be getting hot.

Carl - I can not bypass the filter without replumbing it. As for the WAG, since I can't easily bypass the filter I was thinking about increasing the size of the filter to handle the load, I was thinking something that would handle at least 75GPM since that is what is stamped on the skimmer,.... I did take the filter apart and did the acid wash etc this spring. Everything looked ok. It's in service now and working just fine as far as I can tell. The pressure in the tank when it's totally clean, NO DE, is 13 LBS pressure. After adding the DE it goes to about 15ish.... I don't let the pressure get above 22. So maybe there is a flow restrictor in the input of the filter. The manual says one is supplied but since I didn't plumb the filter I don't know whats in there.... Bottom line, I think the pressure in the filter is low enough that it's not going to blow up or anything. (If I'm wrong yell at me.... ) However, the more I read, the more I believe the filter size needs to be increased.

Mark - The only time I get air in the pump basket is when I vacuum. When I attach the vac hose the pump couldn't draw enough H2O and just struggled. It had a high pitch whine and then the basket lost prime. To solve this problem I drilled a 1/8 " hole in the vacuum plate. Started the pump, and attached the hose. I repeated this, each time making the hole larger, until the H2O flow could keep up with the pump.

Yes I am trying to equalize the flow. I have "massage" jets that the water just trickles out of. Not much of a massage. :-) I have also been playing around with 2 valves in the pipe manifold (returns) I am able to increase the flow to the massage jets, but that causes the pressure in the filter to go up about 4lbs. So I keep that valve open 100%.

Anyway, the more I think about it.. the more I believe that I need to reduce the size of that pump and increase the size of the filter.... I'd rather spend that money on beer with the neighbors, but....

Can I just swap the motor out on my pump? Could I swap it out for a two speed motor? If so, how do I know which motor will fit?

I was thinking that this might be the cheapest/fastest way to fix the issues above.

To reduce delivered HP / wattage consumed you need to swap out the impeller and diffuser, not the motor. A motor will draw current according to the load placed on it -- it's just that if you put a 2HP load on a 1HP motor, it will burn up. However, if you put a 1 HP load on a 2 HP motor, everything will be fine.

Okay, so that sounds even cheaper than chaning the motor. Do I just order the impeller & diffuser from the 1HP version of this pump? How do I know which impeller & diffuser to get?

Look at this page

But, call them, tell them what you have and tell them you want to step down 1 size from your current impeller & diffuser. Let THEM pick everything you need to make it work.

Thanks, I'll give them a buzz, order the parts and update the thread after the pump has been "downsized"
