Can two centrifugal pumps with different outlet pressures and head capacities be connected at their outlets and operated together?
Thread Content
Is it possible to connect the outlets of two centrifugal pumps with different outlet pressures and head levels and operate them together? That is, parallel operation.
For pumps connected in parallel, the outlet pressure should be the same, while for pumps connected in series, the flow rate should be the same.
This is quite difficult to do, as it’s easy for a pump with low head pressure to experience pressure buildup. Of course, if the pipeline after the export parallel connection is thicker and there is no blockage in the subsequent pipelines, the situation might be better.
It’s possible; use an outlet valve to control it so that the two pumps don’t experience pressure buildup.
Parallel connection is primarily used to increase the total flow rate; by enlarging the outlets with low head and reducing those with high head, it is possible to meet the production requirements.
It’s possible, but it’s necessary to ensure that pumps with a low head pressure do not get stuck in a running state; otherwise, the pump will continue to operate without any flow of fluid, causing it to overheat and eventually damaging the pump over time. The control methods mainly affect the opening degrees of the valves at the outlets of the two pumps as well as those on the process pipelines at the pump outlets.
It’s possible to mix oils from different tanks; in all cases, pressure is applied using pumps to send the fluids into the system pipelines. When switching pumps, be careful as there will be significant fluctuations in flow rate, and it’s also necessary to adjust the process accordingly.
Sure! As long as the pump is not under pressure, it’s fine!
Prevent pipeline vibration, as unstable pressure can easily cause damage to the pipelines and equipment.
