What is a coolant pump?

Posted on May 11, 2020

As the name suggests, a coolant pump distributes coolant to targeted places. With the use of a coolant pump, coolant is ensured to go evenly throughout the structure. But do you know what coolant is? Any substance that is used for regulating temperature can be call coolant. Coolant, in most cases, can be either liquid or gas.

The purpose of using a coolant pump is that when the system is running, residual heat is generated. The rise of temperature may lead to severe damage to the working system. Thus, some designers apply different methods to solve the issue. The coolant pump is one of the most effective and convenient measures.

You may also hear a term called heat transfer fluid before. It is essentially the same and is the synonym of coolant in industrial settings. The application of coolant and coolant pump is in a wide range. Therefore, many different designs and styles of coolant pumps can be seen and used on the market.

Sometimes, it makes customers hard to find the most suitable one for themselves. Here is the most comprehensive information you can find. If you want to know more about coolant pumps, make sure you read the following content.

Differences between industrial and vehicle coolant pumps

It is important to differentiate the pumps used in machine tools and vehicle coolant pumps. The function of the two is very similar, but there are still some substantial differences that users can easily distinguish between the two.

1. Similarity

The purpose of using an electric coolant pump in both systems is to distribute coolant/water to cool down the whole working system. The methods are similar as well. A pumping motor is responsible for propelling the water/coolant to the destination.

2. Differences

However, take the pump that is designed for pressurized coolant reactors for example, since the structure of the reactors is more complicated, the design and functions are meant to be much stronger and sophisticated. Since the heat generated by steam has to be cooled down immediately, the efficiency of the coolant pump for a pressurized coolant reactor has to be enough for the task.

On the other hand, the type of coolant pump that you see in your car engines has a more straightforward functional purpose. Most car coolant pumps do not have to worry about minor changes in temperature and working efficiency. Under normal uses, car engine pumps can function without any troubles. The only thing it has to worry about it is to circulate coolant and cool down the motor and engine.

How do coolant pumps work?

Water pumps are mostly powered by electricity and a motor. The impeller is driven by the power to move water/coolant from the source to the targeted area. The motor, on the other hand, determines the speed, moment, and the amount of water/coolant that is distributed to the destination. Surely, the impeller takes part in the action as well.

Application of electric coolant pumps

Applications of coolant pumps are in a wide range, such as air conditioning, industrial cooling system, vehicle cooling system, or household cooling system. Here, we take the application in the machine tool industry, printing industry, plastic industry, and beverage industry as an example.

1. Machine industry

The modern machine industry has a great demand for a wide range of coolant pumps. This is because the pressure and heat generated during each manufacturing process vary greatly. The equipment can only work under normal temperature with the use of a well-designed cooling system. The use of coolant/water pumps varies according to the machining process.

2. Printing industry

Cleanness is what the printing industry requires the most. However, during the printing process, the heat generated leads to dirt and unnecessary defects. All may cause an undesirable print result. In the modern print industry, the use of fine-tuned solutions requires more proper setup and a better cooling system. Therefore, the application of plastic pumps and centrifugal water pumps can solve the issue effectively.

3. Plastic industry

In this specific industry, quick heating is always needed by tempering equipment for the molding process. The temperature can rise quickly from 20° C to over 180° C. The dramatic change of temperature sometimes damages other components of the machine. In this case, the use of compact coolant pumps and an effective cooling system is required. If the temperature around the components cannot be controlled, the life expectancy of the machine can be shortened dramatically.

4. Beverage industry

Some beverage requires a certain and constant temperature to produce. Cold-brew beer and coffee are probably the most well-known examples. If the residual heat in the manufacturing places is not cooled down, the property and quality of the beverage drop immediately. The specially designed electric coolant pump has an in-built automatic cooling system that helps you with everything. It delivers the coolant with a pipe and eliminates the heat for you. Also, the application of plastic water pumps and centrifugal water pumps can solve the issue effectively.
