reeflow snapper?

[rogergolf66]

Ok if I wanted to lower the watt draw on this pump do u do that by restricking the input or out put? And can it be done with a valve or does it have to be done with smaller pipe inlet or outlet?

Never restrict the inlet of any pump unless you want to buy a new pump. As for lowering your watt draw thats doesn't happen unless you make your outlet piping bigger/ shorter and with less restrictions. Depending on your systems and how much restriction you currently have the savings it would be minimal at best.

always restrict the output never the input. a ballvalve works good for this

Some pumps do get more efficent with some head pressure and a ball valve on the outlet only is a good way to do it as others have said.

You will need to measure the amp draw to hit the sweet spot....Let us know how it goes.

That's just wrong. The snapper draws anywhere from 70-105 watts, depending on head pressure, and it draws it's lowest wattage at 11', and max at 4'. (all this is according to the Reeflo website)

what are you looking to gain from doing this? Restricting the snapper down too much leaves you with almost no flow. For what they are made to do, they are pretty efficient. They really weren't made to pump against too much head pressure.

I have a goal of a low watt system is all and I knew that these pumps can pull lower wattage. It is slightly over sized for my system so I thought that would be perfecr. What amp draw would make for lower watt draw?

 

[shifty51008]

have you ever looked into the reeflow blow-hole pumps? they look to have lower watts depending on the settings

Check out the flow charts. They can be found all over the web, and will show you flow vs. watts.
Really on the snapper its only a few watts difference between full flow and max head. amps x volts = watts if I remember correctly. So the less amps it draws, the less watts it will be using.

Everyone thanks for the info
