• By optimizing the shape of the impeller (such as curved blades, flow guide design) and the flow channel structure, it ensures that a matching coolant flow rate is provided under different operating conditions (such as engine idle and high-speed operation), avoiding "overcooling" or "overheating"
• For multi branch cooling systems (such as engines with turbochargers and direct injection), it has sufficient head to ensure that the coolant can flow smoothly through all cooling components such as the water tank, cylinder block, and cylinder head
• Can quickly increase flow rate, shorten warm-up time, reduce cold start wear, and avoid damage to components caused by sudden high temperatures
• The shell is made of high-strength cast iron, aluminum alloy, or engineering plastic (such as PA66+GF), which can withstand long-term corrosion from coolant (including ethylene glycol and preservatives); The impeller is made of wear-resistant plastic or stainless steel to resist the erosion of impurities; Sealing element
• The bearing adopts high-precision ball/needle roller bearings, which are sealed with lubricating grease to reduce the friction coefficient; The impeller has undergone dynamic balance calibration, resulting in minimal vibration during operation
