Pto water pump for pond cleaning

[maddog69]

Hi, I'm thinking about buying a pto water pump from amazon for just under $300. It has plastic impellers and a inch and a half line going in and one going out. I rented a 2 inch trash pump this year to pump silt and old leaves from one of my ponds and it didn't really do the job. I would have to build a simple frame and attach it to my hitch which is easy. It has a keyed shaft that I would have to connect to my pto shaft and was wondering if there was anything like that out there at farm supply stores? Any other thoughts would be most welcome....Thanks! Brad

For cleaning out silt and old leaves, maybe something more like the suction dredges used for gold mining and underwater archaeology would work better.

Here is one article:

I've seen guys irrigate fields with a tractor powered water pump.

Gold dredge would be great....but too expensive.

You need a mud pump or also know as a thrash pump would have a lot larger inlet and outlet high volume low pressure.

As long as the input is the right speed for PTO I think you could make it work. Not sure about the plastic impeller, if you're pumping silt and leaves you might get some rocks which could damage the impeller. The hoses and suction line will probably cost you as much as the pump. Then add on whatever materials you need for a 3pt frame assembly. I mounted my generator on a small utility cart, you might try the same thing. Makes it easy to tow around and stow.
I've had a 2" honda trash pump for 30 years that still works great. Not sure what problem you had with the one you rented, but maybe there was something wrong with the pump. The nice thing about a self powered pump is you don't have to leave your tractor there to power it. I had to leave mine running for days sometimes.

Diaphragm Pumps
Diaphragm PumpDiaphragm pumps work entirely differently than other trash pumps. Instead of using centrifugal force, the pump has a diaphragm which is pushed up and down, creating a vacuum effect.

When the diaphragm goes up, it creates a vacuum, sucking in water. When the diaphragm is pushed down, it ejects the water that was just suctioned into the pump. It essentially acts like a piston in a combustion engine, alternately drawing in and then ejecting out.

Diaphragm pumps are most commonly used to pump sludge and extremely abrasive liquids. A common example would be draining a pond because it can handle the muck and mud on the bottom, as well as the water, leaves and weeds.

big issue is how high do you need to pump the water up to? that alone can make or break many options for you. higher you go. the less options you have.

if your only pumping a couple feet above water level. the mini dredges for gold mining or like would most likely be the ticket. mud/muck does not go through the actual pump. it uses a high pressurized ventri effect. to move mud/muck and water. lots of volume of water, but doesn't really lift water that high.

to go higher...ya looking at sending mud/muck through the blades... it does not take much to jamb up a blade or break it completely off. and in that "trash pumps" normally have a metal blades, and tolerances of say 3/4" maybe up to 1" before jambing up... if ya look at trash pump spec's they normally state how large an object can be before plugging up the pump.

to much mud not enough water = plugged up pipes and hoses. the further you have to move it, the more chance stuff will get clogged up in the pipes and hoses. also the bigger pump you will need to overcome friction (longer hoses/pipes = bad thing)

most pumps generally love to push water, vs sucking stuff up. there are some exceptions in different style of pumps out there.

first time i have ever heard of use of a diaphragm pump used for any sort of sledge.
