- A leak in your system will cause both of these issues. Replace any leaking or damaged pipes and check the water level to make sure that your pump hasn’t exceeded the well capacity. A faulty pressure switch will also cause the motor stay on or cycle too fast. Double-check the settings, and clean the contacts.

- Reverse Rotation. This is where the pump is wired incorrectly meaning the motor runs backwards. When this happens, very little water will be pumped but it does serious damage to the pump, polishing the impeller and leading to cavitation*.
- Dry Running. This is where the water level drops to a point where the pump cannot draw a decent amount of water and/or starts to create a lot of disturbance in the water.
- Running on the Right of the Curve. This is where there is less vertical head than the pump is designed to handle, which makes the pump less efficient.
- Specific Gravity. Submersible pumps are not designed to deal with high levels of solids and will usually quickly fail in slurry applications. Exceeding 1.1 – 1.2 specific gravity is a no-go, this effectively constitutes a sand slurry.
- Clogging. Debris, sediment, and foreign objects can all block up a submersible pump, causing it to fail and leaving you with a frustrating and potentially costly problem.
- Electrical Faults. You may experience issues with the electrical components of your pump, like faulty wiring or motor failure, which can lead to frustrating and potentially costly problems.
- Overheating. When your submersible pump gets too hot, it can spell disaster for your water system, as overheating can cause serious damage and costly repairs.
- Cavitation. Cavitation can wreak havoc on a submersible pump, causing a host of problems that can ultimately lead to failure. When cavitation occurs, air bubbles form in the fluid and rapidly collapse, causing a loud noise and a significant increase in energy usage.
Apr 27, 2016 · The motor runs continuously or too often. A leak in your system will cause both of these issues. Replace any leaking or damaged pipes and check the water level to make sure that your pump hasn’t exceeded the well capacity. A faulty pressure switch will also cause the motor stay on or cycle too fast.
Jul 6, 2017 · Here, we explore the four most common causes of critical failure in submersible motors and what you can do to avoid them. Temperature. Significant changes in temperature, especially overheating, is the most common form of submersible motor failure.
- Changes in Temperature
- The Motor Won’T Start
- Voltage Unbalance
- Reduction in Supply Line Diameter
- Motor Runs Too Often Or Constantly
- Voltage Spike
- Improperly Connected Motor
- Excessive Noise
The overheating of a submersible pump indicates the presence of an underlying problem. A defective motor may be responsible for this problem. However, the overheating may result from another underlying condition which causes other issues alongside raising a pump’s temperature. The fluctuations in pump’s temperature may even result from 1. Incorrect...
A pump’s motor may stop functioning due to a tripped circuit-breaker or blown fuse. You can resolve this issue by installing a new fuse or resetting the circuit breaker.The corroded or dirty fuse receptacles may cause the same problem. However, a motor stops functioning intermittently in this scenario. You can resolve this issue by installing a new fuse receptacle.The deposition of debris or corrosion at the contact points for a pump’s pressure switch causes voltage fluctuations and leads to malfunctioning of the motor. The motor may even stop working. This...The collection of sand or other elements surrounding the pump may prevent it from functioning properly. The amp readings may increase up to six times higher than the normal reading in this scenario...The incorrect sizing of the drop-cables will cause voltage imbalance. It may even result from the unequal transmission of the voltage to each winding. This results in overheating of the motor and decreases a motor’s life leading to critical failure. You can avoid this issue by; 1. Using a properly sized cable. 2. Using a motor which has been design...
Every submersible pump is designed to operate with an input line of specified diameter. However, some users attach a hose or line smaller than the recommended diameter using reduction couplings. The intake line may become crimped in this scenario. It may even become crimped on its own. You can avoid this problem by following these tips. 1. Use an i...
The motor of a submersible pump may cycle frequently or may run constantly in the following scenarios. 1. There is a leak in the system. You have to replace the damaged pipes that are leaking and have to check the level of water to ensure that the well-capacity of the pump is within limits. 2. The pressure switch is defective. You have to examine t...
The motor insulation of a submersible pump has been designed to handle a specified level of voltage. However, the sudden spike in voltage may result from a lightning strike or storm. It may damage the insulation and cause overheating of the motor. The lightning may even form a hole in a motor’s casing. You have to use an external surge protection t...
The impeller of a water pump is supposed to move in one direction. However, a pump cannot operate properly if the impeller moves in the opposite direction. This problem may result from the incorrectly established electrical connections to the electric motor. In this scenario, you have to check the set-up of the electric motor alongside examining th...
If a submersible pump is extremely noisy, then you have to check the valves and have to ensure that the flow pattern has not changed. It may happen due to cavitation in the pump. The excess noise may be the reaction of a pump to the bubbles that are formed when the water is being transferred. The pump will lose its efficiency alongside being extrem...
