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

[PumpTech81]

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.

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

Try a diaphragm pump. See

http://www.hydra-cell.com/product/overview-diaphragm-pumps.html

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

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.

- 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

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.

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.
