Easily Prevent Pump Damage for Your Swamp Cooler
Evaporative coolers, or swamp coolers, are one of the best machines to keep your home or workplace cool.
This is because they are economical to operate and simple to maintain. In addition, the maintenance for swamp coolers is relatively cheap.
The truth is that there are not many cooling appliances that can do as good a job as evaporative coolers. If you have a large area you need to cool, there are limited cooling appliances that can meet your requirements. If you consider an air conditioner, it will provide excellent cooling, but you will need a number of large units to get the job done. The second best option would be industrial fans.
Without a doubt, industrial fans are a decent choice for large areas. But there are a couple of issues in operating industrial fans.
- The first and foremost issue you will face is the number of fans required. To cool a large area you will need lots of fans.
- Secondly, the fans only provide air. If the weather is warm, the fans will blow warm air. They will provide sufficient air but they won't cool effectively.
But when it comes to swamp coolers, you will have an upper hand. You will be able to cool a large area with only a couple of units.
There are some swamp coolers that can cool an exceptionally large area. Even if you end up needing more than one unit, you will not require as many units as when you use industrial fans or air conditioners.
Another reason to get swamp coolers for large areas is that you do not need an enclosed space. To operate air conditioners, you need an enclosed area.
Also, when you are faced with the choice of getting an industrial fan or a swamp cooler, remember that a swamp cooler actually cools the air. It does not just blow air. It actually cools down the environment.
A typical swamp cooler with average specifications can deliver air at a speed of up to 45 miles an hour. This gives swamp coolers the upper hand in cooling almost any type of area as opposed to other cooling appliances.
Watch Out For Dry Run Pump Damage
One of the worst problems you can come across in a swamp cooler is dry run pump damage. Unfortunately, not many people are aware of this type of pump damage.
- The dedicated pumps used in swamp coolers use a centrifugal action to pump water so that it can be sprayed into the air for cooling.
- This pump does not require oil or grease to reduce friction. In fact, its sole source of lubrication is the liquid that it is pumping.
- If the liquid stops flowing through the pump, there will be friction between the internal components. This friction will wear the components down and will result in serious damage to the pump.
- This wear is caused because of severe friction and overheating.
It is commonly believed that if the pump is shut down in time once the water flow ends, the chance of damage could be minimized. This is true to a certain extent.
However, these pumps are designed in a manner that even a brief operational period without the liquid could result in damage.
Causes for Dry Run Pump Damage
Even though dry run pump damage is quite common, it is preventable. The trick here is to identify the causes.
In the case of swamp coolers, dry run pump damage occurs when the reservoir runs out of water. When the reservoir is not able to flow water to the pump, it will run without lubrication. Insufficient lubrication of the pump results in friction and eventually damage.
- First and foremost, you will notice a puddle of water. When it comes to swamp coolers, they are built to handle water. This is why there is a good chance that your swamp cooler itself will not sustain water damage.
- However, the puddle of water may be the cause of damage to other appliances, furniture or even slip and fall injuries.
- You will also see that the swamp cooler will cease to function properly. This is because the internal components of the pump have worn out due to friction.
- Also, there is a seal within such pumps. When the components heat up, the seal starts leaking.
- Once the seal leaks, it is not able to retain water within the pump. When water cannot be retained within the pump, not only do you have to deal with a puddle of water under the cooler, but also insufficient cooling.
- The worst part is that the water puddle can short electrical sockets. It can even result in electrocution. This is why if you come across such an issue with your swamp cooler, have it fixed as soon as possible.
Issues That Can Arise Due To Dry Run Pump Damage
The main concern with dry run pump failure is not related to the seal. The seal is quite easy to replace.
However, there are numerous other issues that can occur as a result of this failure. Let's look at the issues that can arise due to dry run pump failure:
Failure of Electrical Components
Since the water is leaking out of the pump, there is a good chance that electronic components will get damaged.
Even though most of the components of swamp coolers are resistant to water damage, there are others that aren't. In the event water comes into contact with these components, you are looking at a potential electronic breakdown. At times, the electronic failure is so intense that you may need to replace the swamp cooler.
- When the water seal leaks, the water goes into the pump itself.
- The electrical motor works with a bearing inside the pump.
- The bearing is often lubricated with grease. When the water gets into the pump, the grease mixes with water. This water and grease mixture is not suitable for electronic and mechanical components.
- When the bearing comes into contact with the water and grease solution, the bearing wears out. When the bearing is worn out, it has to be replaced.
- At times, the entire motor needs to be overhauled just because of a seal leak.
Preventing Your Pump from Running Dry
There are quite a few ways you can prevent dry run pump damage to your swamp cooler.
If you exercise these precautions, you will be able to save a substantial amount on repairs. Let's look at the methods you can follow to prevent dry run pump damage:
Get a Larger Reservoir
The best thing you can do to prevent dry run pump damage is to get a larger reservoir for your swamp cooler. This will eliminate the chances of water running out quickly.
You will be able to go on for a while without checking the water level in the reservoir. While large reservoirs are a good solution to preventing damage, it is not the only method.
Consider Continuous Water Supply
Another way to prevent this damage to your pump is to ensure a continuous water supply.
- A continuous water supply lets you connect the pump directly to a water tap.
- This eliminates the need to constantly have to fill the reservoir.
- However, there is one disadvantage to this method. In the case of a continuous water supply, the water supply would end if the tab is accidentally shut down. This will cause damage to your cooler in a matter of minutes.
Check for Water Level Regularly
- Monitor the water level on a regular basis.
- Should the water level go down dangerously, turn off the pump immediately.
- This ensures that you have adequate cooling and your pump runs properly for years to come.
Keeping these issues in mind, the manufacturers for most quality swamp coolers have introduced a new safety feature.
Automatic Shut Off
The automatic shut off feature has been introduced in most new evaporative coolers. The sole purpose of this system is to prevent dry run pump damage.
Back in the day, swamp coolers would run out of water. This resulted in the water pump running dry. If the pump is damaged due to a dry run, there is significant repair required, depending upon the intensity of damage.
This is why if the water in a swamp cooler runs out, this system shuts it off. With the help of this feature you can you can leave your swamp cooler unattended. You won't have to worry about having to deal with motor damage if the water runs out. In the event the water runs out, the pump will automatically shut down.
