If you use a centrifugal pump to keep your water tanks flowing, you need to know that your pump will work efficiently. Problems with the pump can interfere with irrigation and water transfer. If you're not familiar with your pump, you might not know how to identify issues. That's where proper troubleshooting comes into the picture. To avoid issues with your water tank, it's important that you know how to identify problems before they lead to a catastrophic malfunction. Read the list provided below. If you're dealing with any of the issues described here, have your centrifugal pump repaired right away.
There's an Issue With Short-Cycling
When your centrifugal pump is functioning the way it should, you can expect a normal pump cycle. The cycle time should be consistent. However, when problems arise, your pump may short-cycle, which means it will cycle on and off in rapid succession. If that happens for too long, your pump can overheat. Not only that but there won't be any water flow. Short-cycling can be caused by several issues including leaking float valves, or low pressure. If your pump is short-cycling, be sure to call for repairs right away.
There's No Impeller Activation
If the motor to your centrifugal pump is running, but the impeller hasn't activated, you won't get any movement in the water. There are actually several reasons why the impeller might not activate. Some of those reasons include air leaks in the suction lines, blockage in the impeller and damage to the pump body. The first thing you should do is check the impeller for possible blockage. If debris is found, clear the blockage and try to run the pump again. If the problem with your pump persists, call for repairs.
There's No Power to the Pump
If you've switched on the power to your centrifugal pump, but the motor doesn't activate, you need to call for repairs as soon as you can. Lack of power doesn't necessarily mean that your pump has failed. In fact, lack of power could be caused by a damaged power cord. Before you call for repairs, check the power cord. If that's not the issue, call for repairs right away. Lack of power could be a sign that the internal motor fault has malfunctioned, or that the pump has overheated. Either way, repairs can alleviate the problem.
If your centrifugal pump isn't functioning properly, now's the time to call for repairs. With timely repairs, your pump can be restored to full function.
