What types of water pumps does RETO manufacture?

RETO designs and manufactures brushless DC (BLDC) water pumps for smart toilets, new energy vehicle thermal management, water heater circulation and boosting, all-in-one water purifiers, ice makers, water-heated mattresses, industrial chillers, macerator systems, beer brewing equipment and coffee machines.

Which certifications does RETO hold?

RETO operates under IATF 16949 and ISO 9001 quality management systems and holds TÜV certification. Products comply with CE, RoHS and REACH. The company is recognized as a National High-Tech Enterprise, an SRDI (specialized, refined, distinctive and innovative) enterprise and a high-growth Gazelle enterprise.

Can RETO develop a customized pump for my application?

Yes. RETO's R&D team includes more than 10 senior engineers, each with over 10 years of industry experience in motor design, control systems, hydraulics and structural design. Custom designs are validated through laboratory and real-application testing before mass production.

What information is needed for an accurate custom pump proposal?

Please share the pumped medium and its temperature range, required flow rate and head, supply voltage, control method such as PWM speed control or FG feedback, duty cycle and expected service life, installation space and port dimensions, noise target, and the certifications required for your target market.

What is RETO's production capacity?

With automated and semi-automated production lines, RETO's annual output exceeds 2 million pump units. Key processes undergo 100% inspection to keep quality consistent across large OEM orders.

Why choose a brushless DC pump instead of a brushed DC pump?

A brushless DC pump has no carbon brushes to wear out, so it typically offers a longer service life, lower operating noise and less electromagnetic interference. Electronic commutation also allows precise speed control, which makes BLDC pumps well suited to continuous-duty appliances and vehicle cooling loops.

Reliable & Durability

Traditional cooling pumps often face the embarrassing situation where an electric water pump humming but no coolant flow occurs due to internal airlocks or motor aging. This "idling" phenomenon can directly lead to battery overheating and even safety hazards. Addressing this industry pain point, we have redefined the product standard. Our liquid cooling pump utilizes advanced brushless motor technology and optimized impeller design, which not only eliminates airlocks but also achieves true maintenance-free operation. It acts like an "artificial heart" for the vehicle—powerful and precise—always ensuring a continuous circulation of coolant.
