Pump suitable for liquid containing 3mm size particles at 400 bar discharge presssure.

Pump suitable for liquid containing 3mm size particles at 400 bar discharge presssure.

(OP)

Dear All,

I am searching for a pump that will be able to operate under the following conditions:

Fluid: Suspension of biomass particles in water (particle size 3 mm and the amount of biomass max 15% by weight of the suspension)
Viscosity: 0.5 - 0.7 Pa.s
Fluid Temperature: 100°C
Discharge Pressure: up to 400 bar
Flow: 10 Lt/h

I have already contacted a dosing pump manufacturer, but unfortunately their pumps can handle up to 1mm size particles.

Thank you.

RE: Pump suitable for liquid containing 3mm size particles at 400 bar discharge presssure.

Good luck. I recommend you speak to a pilot plant designer/manufacturer experienced in feeding biomass at high pressures and low rates.

RE: Pump suitable for liquid containing 3mm size particles at 400 bar discharge presssure.

Try a diaphragm pump. See http://www.hydra-cell.com/product/overview-diaphra... for a typical arrangement. Others make similar pumps. Search for high pressure diaphragm pump.

Also: There's usually a good reason why everyone does it that way

RE: Pump suitable for liquid containing 3mm size particles at 400 bar discharge presssure.

I understand if you can't tell, but I'm really curious for what process you need this. I'd think high pressure AD, but 400bar seems excessive.

MartinLe,

it's for a kind of pilot plant, that's why the flow is so small.

Regarding the pressure, I don't know why is so high, since I am not fully aware of the process.

What does AD stand for? Is it air operated diaphragm pump? If yes, I doubt that these pumps can go up to 400bar.

www.zeton.com - contact them. Trying to do this yourself is going to result in a lot of wasted money and heartache.

Moltenmetal,

When I started this thread I was not fully aware of the specificity of this application.

I agree now, that this is a specialized request.

Thanks for the link.

Try Gardener-Denver- drilling mud pumps

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

RE: Pump suitable for liquid containing 3mm size particles at 400 bar discharge presssure.

AD means anaerobic digestion, there's ideas and experiments to do this at higher pressure for various biological and process reasons.

Sorry for beeing confusing.

RE: Pump suitable for liquid containing 3mm size particles at 400 bar discharge presssure.

I doubt that you can find a pump somewhere. 10 l/h is a very low flow rate but 3 mm particle size is too much for all these small metering pumps. Hydracell is basically a good advice but I do not believe that they can handle the particle size and 400 bar is borderline. I think you need a customized (prototype) pump and that means you will have to pay for the design of it.
