The built-in pump is ideal for water cooling systems. The D5 pump is equipped with an electronic ball motor, which is held in place by a special ball bearing made of ultra-robust ceramic. The pump achieves a maximum flow rate of 1,500 L/h and a delivery head of 3.9 m.

Additionally, the approximately 205 ml capacity tank with stainless steel tubing always ensures sufficient reserves for water cooling. The outer tube of the expansion tank is made of high-quality borosilicate glass, while the lid and bottom are made of durable POM acetal. Inside the reservoir, there is a hollow stainless steel tube that holds the bottom and lid together and serves as the suction point for the pump. The container is designed for both horizontal and vertical orientation, making it perfect for all water cooling enthusiasts.
