Positive displacement pump
Positive displacement pump
(OP)
Does anybody know of any manufactures of positive displacement water pumps capable of around 2-250m^3/hr with a maximum output pressure of about 120psi.
The applications may involve water that has particles upto 10mm in diameter.

RE: Positive displacement pump
To pump the particles, you will probably have to go to a high-pressure piston diaphragm pump like the GEHO that is normally used for pumping slurries.

Is there any possiblity to remove the solids?

What do you mean by "too expensive"? If you need such a pump to dewater a mine to maintain production and keep the workforce safe and it has to be reliable then why is such a pump "too expensive"?
Comments such as this engender a belief that any engineer should not invest in a quality product. That the dollar is an engineering criteria. If all the more competent engineers in the world believed this the likes of Weir, Sulzer, KSB, Toroshima, Mokveld, Noreva and countless other good quality companies would go out of business. Any fool can by a cheap!
It will cost far less than a series of centrifugal pumps where the risk of failure is far higher because of multiple components.

You want it controllable and fairly accurate?
That's a huge range.
RE: Positive displacement pump
Centrifugal pumps could well handle this application but there is insufficient information provided.

RE: Positive displacement pump
Do you have an existing system? What type of pump are you currently using.
Since the solids don't appear to be an issue, the best pump for the application is the vertical turbine pump.
