Many people, upon first encountering a micro water pump, assume, "If it's a water pump, it must be submersible, right?" This assumption isn't necessarily true! Let's discuss this in detail today.

1. First, consider the waterproof rating—this is crucial. 

To determine whether a micro water pump can be submerged in water, you must first consider its waterproof rating, commonly known as the IP rating. It's like buying a phone: some claim to be waterproof, while others can't even touch water. The same applies to water pumps.

IP68: This is the highest level of waterproofing, allowing for full immersion. These pumps are typically fully sealed, like a submarine, making them suitable for applications requiring full immersion, such as changing water in a fish tank or circulating water in a pool.

IP67: Suitable for brief immersion in up to 1 meter of water, but not for extended periods.

IPX4 rating: Only splash-proof, so occasional splashes are fine, but absolutely not submersible.

2. Different pump types have different uses.

Submersible pumps: These are designed specifically for underwater use, like a "swimmer," born to work in water. If you're using them in a fish tank or pool, this is the right choice.

Self-priming pumps: These pumps are more like "shoreside lifeguards," requiring installation on land and drawing water through a hose. Throwing them directly into the water will actually cause them to "drown" and break down.

Circulating pumps: These are more specialized. Some can be submerged, while others can only be partially submerged. The specific requirements depend on the product specifications.

3. Tips for Practical Use

Even if your water pump is waterproof, some precautions should be taken during use:

Keep the power connector dry! This is the most prone to problems, so remember to seal the connector with waterproof tape.

The water temperature should not be too high. Generally, micro water pumps are only suitable for use in room-temperature, clear water. Hot water may damage the seals.

Check regularly. If you notice cracks in the pump casing or aging seals, replace them promptly.

4. Ask Clear Questions When Purchasing

When purchasing, be sure to ask the customer service representative these questions:

"What is the waterproof rating of this pump?"

"Can it be fully submerged in water?"

"How long can it operate continuously in water?"

To summarize:

Whether a micro water pump can be submerged in water depends crucially on its waterproof rating and intended use. Just as not all phones can be used for underwater photography, not all water pumps can be submerged in water. Before purchasing, be sure to read the instructions carefully and ask the customer service representative clearly. This way, you can choose a water pump that suits your needs and provide peace of mind!

Remember: choosing the right pump is more important than choosing the right one! If your application truly requires the pump to be fully submerged, then you must choose an IP68-rated submersible pump. While it may be slightly more expensive, it will provide greater safety and reliability.
