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.

China DC Liquid Cooling Pump for Charging Station Supplier, Manufacturer

A dc motor with water pump assembly acts as the circulation actuator in electric vehicle charging station liquid cooling loops. The pump moves coolant through the charging cable, dispenser connector and power module to remove resistive heat from high-current DC fast charging. Without active circulation, cable temperature rise forces the charger to derate output current.

Product Description

Thermal load and sizing for a dc water pump for project

Extreme Fast Charging systems deliver power at the 350 kW class, per the U.S. Department of Energy (energy.gov). At these levels copper conductors generate heat faster than passive convection can reject. Liquid cooling raises continuous current capacity while reducing cable diameter and weight.

Flow follows Q = P_loss ÷ (ρ × cp × ΔT)

For a 50/50 water–glycol mixture, cp ≈ 3.6 kJ/(kg·K), compared with 4.18 for pure water (engineeringtoolbox.com).

What the data sheet looks like

A typical specification from this product line (Model EWP155F, 12V DC):

Selection rules

✓

Flow head matching — The pump must overcome loop resistance (cable, quick-connect, connector block) while maintaining the required flow rate.

✓

Voltage tier — 12 V DC is common for small charging points; 24 V DC suits higher power cabinets. The model above ships in 12V DC.

✓

Sealing grade — Outdoor dispensers expose the pump to splash and condensation. IP67 covers immersion up to 1 m for 30 min.

✓

Medium compatibility — Pure water or 50/50 glycol mix are both supported; verify chemical resistance of wetted materials.

Where these pumps live in a charging stack

Unlike an rv waste pump that serves a low-pressure freshwater loop, a charging station dc pump runs at higher head against a closed, high-resistance circuit. Compared with a brushless dc motor pump in a solar hot-water panel, the charging pump faces wider ambient temperature swings and stricter noise limits. For users exploring related parts, a solar water circulation pump, a high head dc pump, or a dc water pump 24v may appear in similar searches but serve different circuits.

Frequently Asked Questions

Q1 What does a dc motor with water pump do in a charging station?

It circulates coolant through the liquid-cooled cable and power module to keep connector temperature below the 105 °C limit defined by IEC 62196.

Q2 12V vs 24V — which do I need?

12 V DC suits dispensers with short cable runs and lower heat load. 24 V DC reduces current draw for the same power, easing wiring gauge. The EWP155F shown above is the 12V variant; a 24V counterpart is available in the same series.

Q3 Can the pump run on glycol?

Yes. The EWP155F supports both pure water and water–glycol mixtures. Expect a slight flow reduction with glycol due to higher viscosity.

Q4 What IP rating is required for outdoor dispensers?

IP67 is the baseline for pumps mounted inside or beneath a dispenser enclosure. It covers splash, rain, and temporary immersion.

Q5 How long will the pump last?

The EWP155F is rated for ≥ 20,000 h of operation under rated conditions. Actual service life depends on duty cycle and medium temperature.
