The electric pump is a key component contributing to the laser chiller CWUP-40's efficient cooling, which directly impacts the chiller's water flow and cooling performance. The role of the electric pump in the chiller includes circulating cooling water, maintaining pressure and flow, heat exchange, and preventing overheating. CWUP-40 uses a high-performance high-lift pump, with the maximum pump pressure options of 2.7 bar, 4.4 bar, and 5.3 bar, and a maximum pump flow of up to 75 L/min.
