Creating a Lake

[whodat90]

Are you sure that applies to this type of pump? (I assume it is a centrifugal pump.) My experience using similar centrifugal pumps on a gold dredge is that when the intake is clogged, it just spins at no-load governed speed same as a clogged vacuum cleaner. I don't see how that would stress it. It's easy to notice the increase from 3000 rpm (full load) to 3600 (governed max) that signals it is time to go clean the strainer.

I would think it's less of a strain on the pump as it is an overheat condition. The pump has to get some kind of cooling from the water coming through it, and if you just keep spinning the same water (no flow) it doesn't have a chance to take the heat away?

I don't think so. The engine is air cooled and designed to cool properly at full load, so spinning it faster with no load just blows more air across its cooling fins.

The pump isn't positive displacement, nothing rubs aside from the shaft seal (usually ceramic). Running dry can destroy the shaft seal but there isn't any other effect to cause a heat increase when volume decreases.

DEADLINE IS UP!!! WHERE ARE THE PICS?

You cought me!!

We had to spend some quality time with the family yesterday, so I never had a chance to get down to the lake until we got home. It was almost 5pm and a big storm was on the way, so I wanted to pull the pump and get it put away before dark. No way I wanted to deal with it in the mud.

Shock of shocks, the pump was still running!!! Almost 17 hours non stop. I really felt bad turning it off, but I'm done with it for now.

This morning, the rain guage has over half an inch in it, and I'm at 3/4 of an inch right now with about 40 people supposed to be in at 2pm. I kind of think the hay ride is postponed for a few months, but if we decide to make a mess and go for it, I'll be sure to get some pictures.

Thanks for asking,
Eddie

I saw the weather last night and noticed a big chunk of rain headed your way. I guess the Big Guy upstairs felt sorry for you having to mess with that pump and decided to send some more rain your way for Christmas!

I'll bet you're absolutely right. Too bad it wasn't a few days ago though.

Looking forward to the pictures. I think you're holding out on us just to get a bigger response. All the buildup and anticipation is getting to us.

Eddie,
With all that rain coming your way, I hope your Christmas party won't be washed out. Your pond will surely benefit, but your guests may not.
I hope you will remain dry enough to have a great time anyway.
Merry Christmas,
Rob-

ok what is your official opinion on why it is still working. Do you think the new
spark plug did it or do you think that moving the intake off of the bottom did it. You really for all of us here should put the pump back in after your company leaves and see what causes it to stop so we all know I will chip in 10.00 towards gas for a little knowledge

While everyone is waiting "patiently" for the lake pictures today I hope everyone checks out this nice Christmas Thread.
