How does TOPSFLO TL-C05 water pump win the favor from the global car heater leader?

Car Engine preheater water pump | TOPSFLO Car Auxiliary Water Pump Manufacturer

In Dec, 2022, good news came from the customer “H company”: TOPSFLO engine preheater water pump TL-C05 has passed UL certification together with the heater equipment of H company, and can enter the market in batches! This means that the products of both parties bring more safety and reliability guarantees to the preheater users, and also represents the opening of a new chapter in the story between TOPSFLO and H Company!

What is the background of H company?

It is a well-known leader in car heaters in the world, headquartered in the United States, with branches all over the world.

What is UL certification?

UL has been established for more than 100 years, and its authority has been well recognized. Especially backed by the huge market in the United States, UL standards have almost become the most important quality indicators in the world. UL is mainly engaged in product safety certification and business safety certification business. Its ultimate goal is to obtain products with a certain level of safety for the market and contribute to the guarantee of personal health and property safety. For manufacturers, UL has the highest recognition in the world and provides the most credible product safety testing and certification.

Then, how does the TOPSFLO engine heater water pump relate to the H company's engine heater, and passed the UL certification together?

First contact - initial communication needs

The story begins with the first contact between TOPSFLO sales engineer Irina and H company.

It was the day after New Year's Day in 2016. Irina took the initiative to contact the technical director of Company H to inquire about the need for water pumps. It just so happens that their new generation products is in the research and development stage, and the focus is to break through some technical defects of the original products.

After preliminary communication, Irina learned the water pump they used had the following problems:

1. It’s a AC pump, the efficiency is 2-3 times lower than that of the DC pump, and the volume is large and takes up much space;

2. In the engine system, the liquid containing impurities is easy to cause jamming and wear when passing through the water pump;

3. It is difficult for the AC pump to realize the intelligent control function of the product, such as PWM and FG;

4. The AC pump technical team was not professional enough in support, and the service response was not timely.

In addition to the above problems to be solved, the need for UL certification was also raised.

UL certification is a necessary certification to enter the US market, but it is not a rigid indicator for low-voltage water pumps as components. However, on the basis of having obtained multiple certifications in China, Europe and the United States, TOPSFLO has already made well preparations for UL certification. As long as customers is in need, TOPSFLO team will fully cooperate to help customers realize the verification of the whole machine.

The first-round sample test encountered obstacles

Based on this communication premise, Irina recommended TOPSFLO TL-C01 mini water pump for “H” to test standard parameters.

After testing various performances of the water pump (including flow head, high and low temperature, stalled rotor, power, etc.) by the “H” technical team, it was found that the car water pump needs to be adjusted as follows in order to fully adapt to the new generation heater:

First of all, the pipeline resistance of the heater is relatively large, and a pump with a head pressure of 11M is required, while the standard parameter of TL-C01 is 8M.

Secondly, due to the particularity of the working environment, metal impurities will continuously enter the liquid, causing the relevant contacts of the pump to be stuck or worn.

Thirdly, in order to achieve the purpose of energy saving, high efficiency and environmental protection, the new heater system has a power limit, so the power of the water pump needs to be customized.

Finally, this new heater is an innovation of “H” exsiting product lines, and the functions of automatic signal feedback and intelligent speed regulation need to be added.

The second-round sample test is qualified

Every small adjustment of pump will involve investment in various aspects such as personnel cooperation, development costs, and time cycle, but this is not the point, and the needs of customers are the first for TOPSFLO.

After receiving feedback from “H”, Irina immediately started product optimization work, continuously discussed and verified with the R&D department for three consecutive months, and held several online communication meetings with “H”. In order to achieve the best matching effect with“H” heater, Irina asked “H” R&D team to send the heater system pipeline for testing, and repeatedly debugged the 3D samples, and finally successfully developed the mini water pump TL-C05, realizing a satisfactory customization solution:
