Precautions For Starting Centrifugal Pumps

① The head generated by a centrifugal pump at a certain speed has a limited value. The flow rate and shaft power at the working point depend on the condition of the device system connected to the pump (level difference, pressure difference, and pipeline loss). The head changes with the flow rate.
② Stable work, continuous conveying, no pulsation in flow and pressure.
③ Generally, there is no self-priming ability, and the pump needs to be filled with liquid or the pipeline needs to be evacuated before it can start working.
④ The centrifugal pump starts with the discharge pipeline valve closed, while the vortex pump and axial flow pump start with the valve fully open to reduce the starting power.
