Coolant leakage remains one of the most common failure modes in electric vehicle water pumps, often caused by seal degradation under sustained vibration, thermal cycling, and high-pressure operation. The EWP155F incorporates an enhanced sealing architecture and selected durable materials to help minimize leakage risk over the product's service life. This design approach supports a more secure, lower-maintenance cooling circuit — helping reduce field failure concerns for OEMs and fleet operators.
At just 55W rated power, this Dc Cooler Pump is designed to draw minimal current from the vehicle's electrical system. Lower power consumption translates to reduced auxiliary load on the battery, which can contribute to preserving driving range — a key consideration in EV efficiency optimization.
With a maximum flow capacity of 38 L/min, the pump is built to support rapid heat extraction from high-output battery modules and motor housings. This flow capability helps maintain thermal stability during demanding scenarios such as fast charging, sustained highway driving, and operation in high-ambient-temperature environments.
Vehicle chassis layouts are becoming increasingly packed with components. The EWP155F's compact form factor allows installation in confined spaces near battery enclosures, motor housings, or within modular cooling sub-assemblies — without sacrificing hydraulic performance.
