Various Misunderstandings in the Use of Centrifugal Pumps

If you 're interested in our products, please don't hesitate to contact us. Tel:+86-21-64092786   E-mail: export@croospump.com 1.  Low lift operation of high lift water pump Many people think that the lower the lift, the lower the motor load. In the misleading of this false knowledge, when the water pump is selected, the pump's lift is often high. In fact, for centrifugal pumps, when the pump model is determined, the power consumption is proportional to the actual flow of the pump. The flow of the pump decreases with the increase of the lift, the higher the lift, the smaller the flow and the less power consumed. Conversely, the lower the head, the larger the flow, the greater the power consumption. Therefore, in order to prevent the motor overload, it is generally required that the actual pumping use of the pump shall not be less than 60% of the nominal lift. When the high lift is used to pump water too low, the motor is overloaded and hot, which can burn the m
