Piston pump
Piston pump
(OP)
Hi guys,
I'm desperately looking for a specific pump, but can't seem to find it anywhere. That's why I'm asking here:
I'm looking for a piston pump with following specifications:
- 444 GPM = 100m3/h
- minimum 50 bar
- Can deal with solids up to 100 mm / 4 inches across.
So far I only found the putzmeister HSP1080 which is astonishingly long.
Another type of pump that will do the job would be all right too.
Thanks for thinking with me.

It is up to 100 mm in diameter.
The fluid which will be pumped is dredging fluid. It is scraped of the bottom of small lakes through a grid of 100 mm. Then an Archimedes screw brings the fluid to the piston pump. Suppose I make the grid 50 mm. Will there be other, maybe smaller (in size), solutions?
RE: Piston pump
Piston pumps rely on Check valves. One check in -- and one check out.
Check Valves do not pass particles well. When the solids get caught in the check valve seat, they do not seal. When they do not seal, then they do not work. When they do not work, they can not be used.
Don't pump solids when involving check valves.
Instead, look into a massively expensive progressive cavity pump. They handle solids well.

RE: Piston pump
Progressive cavity pumps handle solids well, too. But not against 50 bar and only as long as these solids do not wear out the stator and that can happen pretty fast at high pressure.
RE: Piston pump
50 bar is a lot. If not for the high pressure, could mammoth pumps be used for such slurries?
RE: Piston pump
The reason for this high pressure is that I want the fluid to be pump over great distances. I've contacted the suppliers you mentioned and await their replies with interest.
RE: Piston pump
I think you need to have a good look at the process and overall system to reduce particle size (a crusher?) or remove the large items altogether. Not many people want to do what you're trying to do so not many vendors will go that far. Slurry on the other hand is a well known and supported industry, but 100mm sized bits at that sort of pressure is not common.
good luck

RE: Piston pump
What diameter is the pipe line?
What is the concentration of the pumped material?
I think you have many questions to answer before even looking at the pump.
