A Leak-Proof Pump for High-Power EV Chargers
We are Sanming Hongfeng Machinery Manufacturing Co., Ltd. We have been operating in Fujian for 23 years with an 8,000-square-meter factory. Although our core business is metal casting and forging, this EV charger liquid cooling circulation pump follows a different technical path. It uses a brushless DC magnetic drive motor. This is a static seal design. There is no mechanical seal with moving parts, which means the risk of leakage is completely eliminated. This is very important for EV charger cooling systems. A leak can damage the equipment and cause safety problems. Our EV charger liquid cooling circulation pump is designed specifically for the cooling needs of high-power ultra-fast charging piles.

Designed for Cooling Fluids and Tough Conditions
This pump is made to move cooling media like ethylene glycol antifreeze, fluorinated fluids, or silicone oil. The flow rate is 2 to 40 L/min. The working pressure is 0.2 to 4 Bar. The temperature range is -40°C to +80°C. This low-temperature start capability is important for outdoor charging in northern winters. The power supply is DC12V to 28V. The protection level is IP65 to IP67, which means it is safe from rain and dust. The design life is at least 20,000 hours. We have built-in protections for over-voltage, over-current, locked rotor, and over-heating. It also supports PWM speed control, so you can easily connect it to your main control system for smart temperature management.

Our Factory Advantage in Materials and Precision
We have our own R&D team. While we are not an electronics company, we have a natural advantage in pump body materials and machining precision. For this EV charger liquid cooling circulation pump, if you need a metal housing, we can use our own casting or forging processes. This guarantees dimensional accuracy and seal surface flatness. Our machining workshop has CNC gantry mills and vertical boring and milling centers. We can achieve a high surface finish on the mounting surfaces and flow channels. This directly affects the pump's efficiency and service life. For quality control, our lab has ultrasonic flaw detectors and magnetic particle testers. We can check for internal casting defects. Every batch is performance tested, and we keep the records to ensure every pump meets the design requirements.
Flexible Cooperation for Your System Testing
Our cooperation terms are very flexible. The minimum order quantity is 1 unit. If you want to take one for system testing, we fully support that. The lead time for a custom sample is about 3 months. The sample fee can be deducted from your future bulk order. We support EXW delivery. Export packaging uses pallets or wooden cases. Payment is 30% upfront for standard products and 50% for custom products. The balance is due before shipping. We arrange technical support before the sale, dedicated order tracking during production, and a 48-hour response time after the sale. Our warranty is 6 months. We are confident that this EV charger liquid cooling circulation pump will run reliably for a long time in your system.
