Thermal Protector Helps Improve Operation Smoothness of Water Pumps

Thermal protection refers to a device set inside a motor or motorized compressor to prevent overheating that could cause a serious failure. Thermal protectors are widely used in water pumps because the pumps are categorized as high-power machines.

In simple terms, the most effective way to avoid water pump overheating problems is to install a thermal protector. This is a one-time investment that might save you unnecessary repair costs.


How Thermal Protector Helps Improve Water Pumps’ Performance

Since water pumps are high-power machines, their motor can easily overheat, paralyzing their operations. Issues like mechanical failure, winding unbalance, and overload will definitely end up damaging your pumps.

A thermal protector could be all the solution you need. Here is how these devices can help you:

ü Avoid the problems of dry burning and extend the service life of water pumps

For water pumps to work efficiently, especially in boreholes, there must be a sufficient level of pumped water. With that, the pump’s electric motor is cooled as the required water pressure is met.

However, the water level may sometimes fall, causing the pump to start sucking air. This is called dry-burning, which can damage the pump or cause complete breakage.

One of the main symptoms of dry burning is overheating. And this could also reduce the life span of your pumps significantly.

A thermal protector features one or several heat sensor elements connected to the motor. It will turn the motor off when the heating starts, saving your pipes. It’s an excellent way to keep your pipes safe.


ü Save time and maintenance costs

A thermal overload protection water pump lasts much longer than one without a thermal protector. We all know how hard and costly replacing a pump can be. It’s not only an inconvenience but also costly.

A high-quality thermal protector like the ST07  can help you avoid all those issues. It controls temperature-rated damages by turning off the motor. This is an automatic system that works without any issues.


The Working Principle of Thermal Protectors In Water Pumps

The working principle of thermal protectors is quite simple. Let us use the ST07, for example. The devices feature copper-nickel alloy bimetal as the core material. It applies basic high-school physics in its operation.

As long as the temperature is below the operating limit, the bimetal disc remains intact, completing the circuit. But if the temperature reaches the maximum operating temperature, it will bend and deform, cutting the circuit. This protects the motor from overheating.

When the temperature drops to optimal, the bimetal resets automatically, reconnecting the circuit. So, the pump keeps operating efficiently and safely.

Why Choose the ST07 from Saftty in a Water Pump

Choosing a high-quality and durable thermal protection unit is crucial. And the ST07, a star model from Saftty, is all that and more. This is a brand well-known for delivering incredible water pump protection solutions. It promises the following benefits:


  • Individually temperature checking

The effectiveness of a water pump thermal protector depends on its operational principle. In this case, the ST07 outperforms other brands because it checks individual temperatures. That means it will detect the issue much faster before it becomes a huge concern. They are extremely temperature sensitive and respond to temperature changes with uttermost accuracy.

  • Top-tier raw materials

A poor-quality thermal protector can easily break when the temperature changes get too frequent. The ST07 is designed with high-quality material to ensure endurance and longevity. This gadget lasts so long you can completely forget about repairs and maintenance.

  • Repeatable temperature performance

The thermal protector offers a long cycle with repeatable temperature performance. That means you can use it several times to regulate temperature issues, and it will still perform effectively. Some thermal protectors only have a single use, and that would mark their end.

  • Gasketed steel case

The gasket steel case on this device makes it perfect for more impregnation processes. You are looking at the best-performing thermal protector on the market.

  • Various selection of leads and insulating sleeves

It’s not by accident that the ST07 is the most durable thermal protection on the market. The various sections of leads and insulating sleeves give it a long life and ensure top-notch protection for your water pumps.


The pump industry is finding more and more reliance on motor thermal protector devicesBut since there are so many products on the market, it’s easy to choose the wrong one and have a not-so-pleasant experience. Choosing the Saftty ST07 means avoiding all those issues.

Saftty is a pioneer brand in this market that integrates high-end innovations and quality to bring you ultimate pump protection. If you have questions about the ST07, don’t hesitate to ask – a friendly customer support system is on standby.
