Can the discharge at the bottom of the pump be opened while the centrifugal pump is running? Will it have an impact on the pump?
Do not open the bottom discharge of the centrifugal pump during operation, as this will affect its proper functioning and may lead to a decrease in pressure inside the pump as well as a reduction in flow rate. .
Firstly, this bottom discharge function is used to remove the residual liquid when the pump is at rest; it is usually necessary to drain this residual liquid during maintenance or when the pump is shut down in winter to prevent freezing. You can say that it’s not impossible to open it on normal days, but it’s useless. It only shows low pressure at the outlet; for reference only.
When it is released, less water comes out; more water is drawn in instead
I want to check if the pump’s discharge is unobstructed
