Common Causes and Solutions for Pumping System Issues – Tabelle
| Cause | Description | Possible Solutions |
|---|---|---|
| Blockage in the discharge line | A blockage in the discharge line occurs when there is an obstruction that prevents the flow of fluid from the pump. This can be caused by debris, sediment, or a buildup of material. | – Inspect and clean the discharge line to remove any blockages. – Use a high-pressure water jet or air compressor to clear the blockage. – Install a filter or strainer in the discharge line to prevent future blockages. |
| Valve misalignment | Valve misalignment refers to the improper positioning or alignment of valves in the pumping system. This can result in reduced flow, increased pressure drop, and inefficient operation. | – Check the alignment of all valves and realign if necessary. – Ensure that valves are fully open or closed to allow for proper flow. – Replace any faulty or malfunctioning valves. |
| Improper pump selection | Improper pump selection occurs when the pump chosen for a specific application does not meet the required specifications. This can lead to inadequate flow, inefficiency, and premature pump failure. | – Evaluate the specific requirements of the application and select a pump that meets the desired flow rate and head. – Consider factors such as fluid properties, system pressure, and operating conditions when selecting a pump. – Consult with a pump expert or engineer for assistance in pump selection. |
| Closed isolation valve | A closed isolation valve refers to a valve that is completely shut, preventing any flow of fluid through the system. This can result in no flow or low flow rates. | – Check the position of all isolation valves and ensure they are fully open. – Inspect the valve mechanism for any faults or malfunctions. – Replace any faulty valves or repair the existing ones. |

FAQ
What does dead heading a pump mean?
A dead-head occurs when a centrifugal pump runs without any flow because the discharge valve is closed or blocked. This causes the water to circulate within the pump repeatedly, leading to an increase in water temperature. The excessive heat generated can harm the costly seals and greatly diminish the pump’s lifespan. It is important to prevent dead-head situations to avoid these damaging effects.
Can you dead-head a gear pump?
Gear pumps, as a type of positive displacement pumps, should not be operated without a fluid outlet, as this can cause immediate damage. However, there is an exception for gear pumps when dealing with low viscosity fluids. In such cases, the fluid slipping back through the pump actually helps relieve pressure and provides a pathway for the fluid to flow. So, it is important to ensure that there is always a place for the fluid to go when operating gear pumps.
Can you deadhead a hydraulic pump?
If a pump is not properly maintained, it can potentially cause explosions due to excessive hydraulic energy buildup. This can occur when the pump is not adequately primed, causing it to run without sufficient fluid. Additionally, extended periods of dry operation can result in cavitation, further increasing the risk of explosions. It is important to regularly inspect and maintain pumps to prevent these potentially dangerous situations. (23rd August 2021)
Can you deadhead a piston pump?
In general, the pumps can operate smoothly without any issues with the pistons until the end play reaches a measurement of 0.006 inches (0.152mm). It’s important to note that the swashplate, which is responsible for regulating the pump’s performance, undergoes continuous adjustments while the pump is in operation. To ensure accurate readings, the pump is put into a deadhead condition, which stabilizes the swashplate before taking any measurements.
