Silent water pumps revolutionize medical cooling systems and improve patients' treatment experience and quality of life. This is exactly how TOPSFLO helped a medical technology company achieve great success.Through an excellent technical team and high-quality products, the noise problem has been solved and a revolutionary breakthrough has been brought to the medical equipment industry.

Let's take a look at the story of the cooperation between TOPSFLO and D Company, and see how they launched a silent water pump with high performance and low noise, and how they brought positive changes to patients' health and quality of life through innovation.

Needs and challenges
Company D is a listed medical technology company in Europe, focusing on the development, production and sales of advanced medical cooling systems, aiming at minimizing hair loss and improving the health and quality of life of cancer patients during chemotherapy.

In 2020, the R&D center of company D put forward a request to TOPSFLO sales engineers by email: their new generation cooling system needs an adjustable speed silent water pump for circulating coolant.

The water pump plays a vital role in company D's system. It is used to precisely control the temperature of the cooling system to ensure the effective shrinkage of blood vessels that directly contact the patient's skin and reduce the damage of chemotherapy to hair follicles.

However, the American brand water pump used by company D was only slightly noisy at first. With the long-term use of the equipment, the noise of the water pump gradually increased, and the hospital received complaints one after another. The noise of the equipment affected the treatment effect of patients. Because cancer patients themselves are under tremendous emotional pressure during chemotherapy, the increase in equipment noise makes patients more emotionally unstable.

This problem seriously deviates from the corporate values of D company - "Put patients first and care about customer experience". Therefore, the customer embarked on a "pump search" to find a replacement pump.

Many attempts and disappointments

Before finding TOPSFLO, Company D tested some water pumps from the United States, Germany and China, including many branded water pumps.
However, in tests, the noise of these pumps did not have much advantage over the pumps they were originally used in, and even exceeded the 55dB(A) noise standard (tested at a distance of 0.5m). Company D has asked these companies to reduce the noise to below 55dB(A), but has not received any response. They also tried various methods to reduce the noise, but the results were not satisfactory.

Until they accidentally learned about the TOPSFLO silent pump from a British friend, they sent TOPSFLO a consultation email with the mentality of trying it out.
Solutions and surprises

Combined with D company's flow, head and speed regulation requirements, TOPSFLO engineers recommended brushless centrifugal pump TL-C01 to the customer.

The maximum head is 23psi, the flow and power requirements at the operating point of 3.5V, and the speed regulation and noise requirements. TOPSFLO electronic engineers, electrical engineers and structural engineers simulated the application conditions and environment of D company according to customer needs, and formulated a professional matching plan. After the plan was finalized, TOPSFLO first conducted a number of tests on the performance, temperature rise and noise of the pump in its own CNAS-level laboratory, including 150,000 on-off tests.

Internal evaluation shows that the TOPSFLO water pump can fully meet the customer's needs, and can realize 5V/PWM speed regulation, FG speed signal feedback, especially the noise level of only 49dB(A) at the maximum speed, which is 7dB lower than the water pump used by the customer before (A)! Company D conducted a test immediately after obtaining the samples, and the results showed that the performance of the TOPSFLO water pump not only fully matched the working requirements of its equipment, but also the noise was even lower than 49dB(A) under 3.5V speed regulation.

At that moment, company D's laboratory cheered happily. After such a long search, they finally found a silent water pump whose noise was much lower than the requirement. It was really exciting. Company D immediately sent an email to the sales engineer of TOPSFLO, expressing its amazement at the mute effect of the water pump.
Long-term reliability verification and successful switching

Of course, this is just a good start.
Company D, like TOPSFLO, pays great attention to product quality and long-term reliability verification.
Equipment in the medical industry also needs to undergo multiple certifications such as EMC testing, clinical validation, and FDA approval. TOPSFLO has conducted more than 20 tests on the TL-C01 water pump in the company's internal laboratory, including a life test of up to two years and continuous operation of more than 20,000 hours, a high temperature aging test of 100°C for 3,000 hours, salt spray test and high and low temperature shock test etc.
In addition, TOPSFLO pumps have also obtained REACH, ROHS certification, FDA certification, NSF food grade certification and the most stringent WRAS certification in the UK, making the European and American markets more competitive for customer equipment.

Adhering to the spirit of craftsman, TOPSFLO always puts product quality in the first place, and takes it as its responsibility to let customers use it with peace of mind. And company D has also conducted reliability verification on the equipment side, avoiding the trouble of noise problems after long-term use in the past.
After one and a half years of internal and external verification, the TOPSFLO water pump has demonstrated excellent performance and stable noise performance, and has received positive clinical feedback. Therefore, at the end of 2022, D company resolutely switched all the water pumps of its product cooling system to TOPSFLO water pumps, and continued to introduce TOPSFLO products in new projects.
The person in charge of D company said that he once believed that the water pumps made in China could not be compared with European and American products, but the excellent technology and high-quality performance of TOPSFLO water pumps completely subverted his traditional views on Chinese manufacturing and solved their problems. All this is really rare!

Epilogue
Through cooperation with TOPSFLO, Company D finally solved their problem and found a silent water pump, which effectively reduced the noise level of the cooling system. Through its professional engineer team, advanced testing equipment and strict quality control standards, TOPSFLO provides customers with high-performance, low-noise solutions that meet customer needs and win their trust. This story fully proves TOPSFLO's technical advantages and excellent product quality in the field of medical cooling systems, and has established a good reputation for the industry.

On the road of manufacturing in China, TOPSFLO moves forward firmly and bravely faces challenges, making domestic water pumps shine brightly in the medical industry at home and abroad. TOPSFLO believes that through continuous efforts and pursuit of excellence, they will provide more advanced solutions in the medical field and contribute to the health and quality of life of patients.
