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.

Public DC fast chargers (150-350 kW) and megawatt-class connectors generate heat proportional to current squared. Air cooling is impractical past roughly 250 A per conductor. A cooler water pump motor circulates glycol through cold plates and liquid-cooled cables to hold connector temperature rise inside standard limits.

Global public fast and ultra-fast chargers reached 2.2 million units in 2025 , and the U.S. DOE AFDC recorded 73,951 public DC ports by mid-2026. More high-power ports mean growing demand for reliable circulation pumps.

Product Description

Cooler Water Pump Motor Working Principle in the EVSE Loop

An automotive electric water pump sits between the reservoir and radiator, generating head to overcome hose friction and elevation. The EWP060F features a brushless DC centrifugal design that pots the electronics and runs the rotor wet, ensuring no shaft seal can leak. Speed is easily modulated via PWM or LIN control based on contact-temperature feedback.

How to Select an Auto Electric Water Pump for a Charging Pile

Pump selection starts with hydraulic demand rather than motor size. For the EWP060F, its 45 L/min flow and 9m head make it ideal for standard 12V EV charging cabinet loops. You must sum the pressure drop across the cable, couplers, cold plate, and radiator at target flow to ensure the pump operating point is stable.

Correct sizing prevents cavitation. Seals must resist pure water or antifreeze up to 100 C. With an IP67 rating, the EWP060F ensures high reliability in outdoor cabinets. Related options include magnetic-drive gear pumps for silicone-oil runs or high-temperature glycol pumps.

Reliability Data and Applicable Standards

Service life is set by the temperature profile; the EWP060F is rated for over 20,000 hours of continuous operation under defined loads. Applicable references include IEC 61851, SAE J3400 connector thermal limits, and the NREL-CharIN megawatt charging evaluation. Specify an auto electric water pump that has passed identical vibration and temperature-cycle tests.

Frequently Asked Questions

Q1Why choose a brushless pump over a brushed motor in an EVSE?

A: Brushless designs remove commutation wear and EMI spikes, giving longer life and stable PWM speed control.

Q2What happens if the cooling loop still holds air after servicing?

A: Air pockets cut flow and cause cavitation noise. Bleed the highest-point valve before start-up.

Q3Does a higher glycol share change the pump sizing?

A: Yes. Viscosity rises with glycol share, increasing required head. Derate flow by roughly 5-10% at a 50% concentration.

Q4Is IP67 enough for an outdoor charging cabinet?

A: IP67 covers temporary water immersion. For outdoor cabinets, ensure the housing material and cable-gland rating also resist UV and chemical exposure.

Q5Can one 12V pump feed both the power module and the liquid-cooled cable?

A: Only if the combined pressure drop stays within the pump performance curve. Parallel branches usually require balancing valves.
