The Considerations Behind Shrinking Pump Outlets Benefits and Risks

If the calibre of the pump outlet is changed from 1’ to 8 points, will this change affect the pump? In fact, reducing the pump outlet will not have a serious impact and may even slightly increase the water pressure. However, due to the increased flow rate of the pump, it will lead to some hydraulic losses. The following will explore the possible impact of narrowing the pump outlet: Narrowing the pump outlet will bring the following changes: 1. Narrowing the outlet is equivalent to partially closing the outlet valve, so that the pump pressure rises, the flow rate is reduced, and the current may also be slightly reduced. However, if there is vibration of the pump, the vibration situation may not be reduced, and may even be aggravated; 2, pump outlet narrowing will not change the pump head, but if the external environment changes, it may affect the overall performance of the pump, which may lead to an increase in outlet pressure. This change is dynamic, it can be said that narrowing the outlet has a throttling effect, so that the outlet pressure increases; 3, if the working conditions of the site conditions are not good, narrowing the outlet may affect the service life of the pump, but if the pump after the change is still in normal condition, there is no need to be overly concerned; 4, as long as it is not overly narrowing the outlet changes usually do not cause problems. However, if the changes are too large, it may cause poor water discharge, increase the pump pressure and motor load, may lead to motor overload; 5, changes in the size of the outlet will directly affect the pump flow, usually the larger the outlet, the larger the flow, and vice versa.
