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.

Frequently Asked Questions (FAQ)

How does this design eliminate electric vehicle water pump coolant leakage?

Traditional cooling pumps frequently suffer from seal degradation under persistent thermal and mechanical stress. Our pump utilizes high-grade structural sealing technologies and heavy-duty wear-resistant materials, effectively eliminating leak points and safeguarding high-voltage battery modules from catastrophic liquid ingress.

What are the temperature limits and environmental protection ratings?

The pump is engineered to endure harsh conditions, operating continuously in ambient temperatures from -40°C to +125°C and medium temperatures from -40°C to +100°C. Coupled with an IP67 rating, it delivers full protection against dust ingress and water submersion.

What control and feedback interfaces are supported by this pump?

The unit integrates PWM (Pulse Width Modulation) for continuous and precise fluid regulation according to vehicle thermal demand, along with an FG speed feedback signal that permits vehicle electronic control units (ECU) to monitor real-time rotational speed.

What built-in electrical and motor protections are included?

It features comprehensive circuit safeguards including overcurrent protection, overvoltage protection, locked-rotor defense, over-temperature cutoff, and reverse polarity prevention to ensure safe operation throughout its ≥20,000-hour service lifespan.

How quiet is the pump during standard operation?

Operating at or below 45dB at a 1-meter distance, the pump minimizes NVH (Noise, Vibration, and Harshness) levels, preventing cabin noise disturbances and maintaining a quiet driving atmosphere.
