This may be a stupid question but I have to ask for my own sanity. If the fluid is "free flowing" through the pump, the impeller would spin in the same direction as it would if it were in operation (from suction to discharge), correct? And if it were to spin in the same direction why would it...
Thanks again. I appreciate the help. I know some people are looking for some details on the pump but unfortunately I have spec'd out a pump yet so I cant provide these details. I have simply worked out the hydraulics and realised that with the varying densities the requirement of a pump may not...
Thank you everyone. I am going to simply approach this as the pump being a head loss to the overall system. When the pump is not need I will have a "clutch" to remove it from the motor so it can spin freely. I will be mindful of the pumps RPM when free flowing though.
Thank you.
densities range from 1010kg/m3 to 1300kg/m3. The pump would not be running in reverse. The fluid would simply be running through pump. (no work required on the system)
Hello. I have a situation where my system will sometimes need a pump but other times the fluid wont require the pump to move the fluid. This is caused by varying densities of fluid being moved. If I always allow for fluid to be on both the suction and discharge ends of the pump can any...
