TOPSFLO successfully solved the long-standing pump stuck problem for a leading Korean water heating mattress manufacturer. With outstanding reliability and zero stuck failures over three years, TOPSFLO’s C03 quiet DC circulating pump earned strong customer recognition and secured a 100,000-unit annual order.

TOPSFLO Secures 100,000-Unit Annual Order from Leading Korean Water Heating Mattress Brand

Recently, TOPSFLO received a major annual order of 100,000 units from a well-known Korean company specializing in water heating mattresses. At the same time, the customer sent a commendatory email highly praising the performance of 150,000 TOPSFLO quiet DC circulating pumps used over the past three years.

Compared with other suppliers, TOPSFLO’s C03 Water Heating Mattress circulation pump stood out for its exceptional reliability, zero stuck failure rate, and consistent product quality. It successfully solved the long-standing rotor jamming problem that had affected the customer’s previous systems.

Water Heating Mattress Technology and the Role of Circulating Pumps

Water heating mattresses, also known as temperature-controlled plumbing mattresses, mainly consist of a water reservoir and a plumbing mattress.

The system uses a brushless DC mini water circulation pump to circulate warm water from the reservoir through the mattress, providing stable and comfortable heating. Because water is used as the heating medium and no electromagnetic radiation is generated, this technology is especially suitable for children and the elderly.

According to Statista, demand for smart home comfort products and intelligent heating solutions continues to grow globally, driving increased demand for reliable circulating pump systems.

As the core power unit of the system, the circulating pump directly affects:

• Heating performance

• Noise level

• Product reliability

• User experience

However, many products on the market still face issues such as uneven heating and startup failure after long-term storage, often caused by pump jamming.

Solving a Common Industry Challenge

To solve this industry-wide challenge, the Korean customer evaluated multiple miniature pump suppliers, but most failed to meet its strict requirements.

After recommendation from a trusted partner, the customer approached TOPSFLO and challenged its engineering team to solve the stuck pump problem.

After more than one year of R&D and testing, TOPSFLO developed three key technical improvements.

1. High-Precision Components and Manufacturing

TOPSFLO uses premium raw materials and precision molds imported from Japan to ensure high consistency in rotor shafts and bearings.

This greatly reduces dimensional deviation and minimizes the risk of mechanical jamming.

2. Optimized Internal Structure

The pump’s internal structure was redesigned to improve impurity tolerance while maintaining ultra-low noise and stable performance.

This allows the pump to operate smoothly even in more challenging conditions.

3. Powerful Motor with Intelligent Startup

TOPSFLO integrated a high-torque motor with advanced startup control technology.

This provides stronger startup force and ensures smooth operation even when minor impurities are present.

Strong Customer Recognition

The results proved highly successful.

Over the past three years, 150,000 TOPSFLO water heater mattress pumps have operated with:

• Zero stuck failures

• Stable heating performance

• Excellent reliability

• High customer satisfaction

This outstanding performance secured a new annual order of 100,000 units and further strengthened the partnership.

Why Customers Trust TOPSFLO

With over 20 years of experience in micro pump development and manufacturing, TOPSFLO continues to deliver reliable pump solutions for heating, cooling, medical, and industrial applications.

TOPSFLO believes that only through continuous innovation, precision manufacturing, and strict quality control can long-term customer value be created.
