Can a 12v pump work at 15v voltage? Can a 24v pump work at 30v voltage?

We suggest you use the pump under its rated voltage. Usually, a 12v pump can typically work between 5v~13v; a 24v pump can typically work between 5v~26v. If the voltage exceeds this range, we can not guarantee its lifespan.

However, we can customize the operation voltage according to your needs. Contact us to learn details.

Can I use a car battery as the power supply for the pump?

Please note that many batteries will exceed their rated voltage when fully charged. Make sure the voltage does not exceed 13v for a 12v pump and make sure the voltage does not exceed 26v for a 24v pump. If you are not sure, I suggest you must use a multimeter to measure when the battery was fully charged.

Is the pump materials compatible with ozonated water?

The material of the pump impeller is POM which’s material compatibility with Ozone is C. Fair — Moderate Effect. We don’t recommend you use it for continuous running. For long-term operation, we suggest you change the impeller material to PC; it will be perfect with Ozone water. Contact us to get more details.

Could you please provide the material list of the main parts of the pump?

The housing is PA66.

The impeller is POM.

The shaft is ceramics.

Why is your price higher than others?

You Get What You Pay For.

The competition in the Chinese manufacturing market is very intense. Some factories specialize in copying other people’s products. But they don’t have the core technology, just make the same appearance. And most of the time, they used inferior raw materials and cut corners.

Don’t be cheated by price; there are a lot of things more important than it, we will give you products with high cost-effective.
