NF GROUP 24V 240W Low Voltage Electronic Water Pump For Electric Vehicles
Description
An electronic water pump (EWP) is a critical component in modern vehicles, primarily used to circulate coolant through the engine and thermal management systems.
Unlike traditional belt-driven pumps, EWPs operate via an electric motor, enabling precise control over coolant flow.
Key applications include:
Engine Cooling – Maintains optimal operating temperature, preventing overheating.
Hybrid/Electric Vehicles (EVs) – Cools batteries, motors, and power electronics for efficiency and longevity.
Start-Stop Systems – Ensures coolant flow even when the engine shuts off, reducing wear.
Turbocharger Cooling – Prevents heat buildup in high-performance engines.
Thermal Management – Integrates with smart systems for energy-efficient heating/cooling.
Electric Water Pumps consist of the pump head, impeller, and the brushless motor, and the structure is tight, the weight is light.
Vehicle electric water pumps are widely used for cooling the motors, controllers and other electrical appliances of new energy vehicles (hybrid electric vehicles and pure electric vehicles).
NF GROUP Auto Electric Water Pumps have advantages shown below:
*Brushless motor with long service life
*Low power consumption and high efficiency
*No water leakage in magnetic drive
*Easy to install
*Protection grade IP67

Function Description
| 1 | Locked rotor protection | When impurities enter the pipeline, the pump is blocked, the pump current suddenly increases, and the pump stops rotating. | |||
| 2 | Dry running protection | The water pump stops running at a low speed for 15min without circulating medium, and can be restarted to prevent the damage of the water pump caused by serious wear of parts. | |||
| 3 | Reverse connection of power supply | When the power polarity is reversed, the motor is self protected and the water pump does not start; The water pump can operate normally after the power polarity returns to normal | |||
| Recommended installation method | |||||
The installation angle is recommended, Other angles affect the discharge of water pump. |
|||||
| Faults and solutions | |||||
| Fault phenomenon | reason | solutions | |||
| 1 | Water pump doesn’t work | 1. The rotor is stuck due to foreign matters | Remove the foreign matters that cause the rotor to be stuck. | ||
| 2. The control board is damaged | Replace the water pump. | ||||
| 3. The power cord is not connected properly | Check whether the connector is well connected. | ||||
| 2 | Loud noise | 1. Impurities in the pump | Remove impurities. | ||
| 2. There is gas in the pump that cannot be discharged | Place the water outlet upward to ensure that there is no air in the liquid source. | ||||
| 3. There is no liquid in the pump, and the pump is dry ground. | Keep liquid in the pump | ||||
| Water pump repair and maintenance | |||||
| 1 | Check whether the connection between the water pump and the pipeline is tight. If it is loose, use the clamp wrench to tighten the clamp | ||||
| 2 | Check whether the screws at the flange plate of the pump body and the motor are fastened. If they are loose, fasten them with a cross screwdriver | ||||
| 3 | Check the fixation of the water pump and the vehicle body. If it is loose, tighten it with a wrench. | ||||
| 4 | Check the terminals in the connector for good contact | ||||
| 5 | Clean the dust and dirt on the external surface of the water pump regularly to ensure normal heat dissipation of the body. | ||||
| Precautions | |||||
| 1 | The water pump must be installed horizontally along the axis. The installation location should be as far away from the high temperature area as possible. It should be installed at a location with low temperature or good air flow. It should be as close to the radiator tank as possible to reduce the water inlet resistance of the water pump. The installation height should be more than 500mm from the ground and about 1/4 of the water tank height below the total height of the water tank. | ||||
| 2 | The water pump is not allowed to run continuously when the outlet valve is closed, causing the medium to vaporize inside the pump. When stopping the water pump, it should be noted that the inlet valve must not be closed before stopping the pump, which will cause sudden liquid cut-off in the pump. | ||||
| 3 | It is forbidden to use the pump for a long time without liquid. No liquid lubrication will cause the parts in the pump to be lack of lubricating medium, which will aggravate the wear and reduce the service life of the pump. | ||||
| 4 | The cooling pipeline shall be arranged with as few elbows as possible (elbows less than 90 ° are strictly prohibited at the water outlet) to reduce pipeline resistance and ensure smooth pipeline. | ||||
| 5 | When the water pump is used for the first time and used again after maintenance, it must be fully vented to make the water pump and suction pipe full of cooling liquid. | ||||
| 6 | It is strictly prohibited to use liquid with impurities and magnetic conductive particles larger than 0.35mm, otherwise the water pump will be stuck, worn and damaged. | ||||
| 7 | When using in low temperature environment, please ensure that the antifreeze will not freeze or become very viscous. | ||||
| 8 | If there is water stain on the connector pin, please clean the water stain before use. | ||||
| 9 | If it is not used for a long time, cover it with a dust cover to prevent dust from entering the water inlet and outlet. | ||||
| 10 | Please confirm that the connection is correct before powering on, otherwise faults may occur. | ||||
| 11 | The cooling medium shall meet the requirements of national standards. | ||||
