Low flow / high head requirements

[joisy]

Dear All

can you please advise me the vendor, which can supply the pump with 1 - 5 cub.m/h flow, 55 barg out and 2 m NPSHA. Assume that we should come up with positive displacement pump.

thanks,
Joisy

Centrifugal pumps could be used (depending on the viscosity). For heads of about 3000 ft, special high-speed centrifugals could be used. Best is to contact reputable manufacturers to ask for quotations.

joisy, Do a web search for piston pumps. There are many styles of multi stage units that can get you into pressure and flow range you're looking for.

I have used Sundyne high speed centrifugal pumps in similar application with excellent results.

joisy,

Another alternative centrifugal type is the Rotary Pitot Tube type which is manufactured by Roto-Jet, which I think is owned by Weir Pumps now.

Assuming clean fluid, no solids, a Goulds 3935 centrifugal multistage is a good pick. Very competitive in this flow range and cheaper than a recip style.
