Multistage pump selection
Thread Content
There are two operating conditions for the selection of a multi-stage pump: 1. Acidic water containing chloride ions; the material of the flow-through components is 2507, the density of the medium is 1050 Kg/m3, the normal flow rate is 22 m3/h, the operating temperature is 40°C, the inlet pressure is 2 MpaG, and the outlet pressure is 4 MpaG. I would like to know whether a pump compliant with API610 BB4 can be used for these conditions? What are the efficiency and installed power? 2. The medium is acidic water containing chloride ions; the material of the flow-through components is 2507, the density of the medium is 1050 Kg/m3, the normal flow rate is 22 m3/h, the operating temperature is 40°C, the inlet pressure is 0.6 MpaG, and the outlet pressure is 6 MpaG. I would like to know whether a pump compliant with API610 BB4 can be used for this application? What are the efficiency and installed power?
BB5 would be better, I think. Find a pump supplier and have them come up with a proposal based on the design specifications; wasn’t it specified which design to choose?
Are there any samples of multi-stage pumps for reference?
Q=22, H=190m: Efficiency=42, Shaft power=30.5 kW; Motor power=37 kW. Q=22, H=514m: Efficiency=48, Shaft power=71.4 kW; Motor power=90 kW
Is it a normal requirement at the inquiry stage to ask pump manufacturers to provide performance curves?
