Insufficient Centrifugal Pump Flow

In addition to some problems occurring in the fluid, the insufficiency of the flow rate, namely the centrifugal pump capacity, may also cause pump failure. Insufficient centrifugal pump flow may cause the following possible malfunctions;

• Air may remain in the suction part of the pump. In this case, the pump suction part must be filled with water. The purpose here is to expel the air inside.
• Air may remain in the suction part of the pump. In this case, the pump suction part must be filled with water. The purpose here is to expel the air inside.
• Suction height may be too high. The pump may need to be primed from a lower level to clear the fault.
• Check the suction circuit or stuffing box. There may be a leak caused by the circuit or the box.
• Air may be leaking from the packing. Likewise, the packing may be worn out. Wear and tear also cause malfunctions.
• The suction or discharge valve may be partially closed or there may be some mechanical damage. For example, a damaged pump impeller.
• Speaking of pump impeller, let’s add the following item. The impeller may be partially clogged. You may need to check. Another problem caused by the impeller may be related to the assembly; If the impeller is reversed, the fault may be caused by this.
• In addition, if there is excessive sucking difficulty, this is also a cause of disruption. (Cavitation)
• Is sufficient distance left for the suction strainer? If there is not enough space for the suction strainer, it may malfunction. The strainer to be used in the suction line should not be too close to the pump inlet flange.
