This bundle includes the HEATKILLER Tube Reservoir and D5 PWM pump. The HEATKILLER Tube Series is a modular series of high end reservoirs with a glass tube made from borosilicate glass. It has some outstanding features which are listed here. Borosilicate glass tube Borosilicate is a glass with very high chemical and thermic resistance. It is scratch-resistant and has very low heat expansion. These outstanding features make borosilicate an ideal material for reservoirs. Reservoir Technical data Material cover: POM Material struts: black anodized aluminium Tube: borosilicate glass Material bottom: POM Material Inlay: stainless steel Measurements (L x W x H): 70 x 70 x 253,4 mm Tube length: 150mm Tube diameter: 65mm Capacity: aprox. 375ml Weight: aprox. 790g Seal: NBR, VMQ Connection thread: 2x G ¼ inch (DIN ISO 228-1) The WCP D5-PWM is a DC pump using the spherical motor design as developed by Laing. The only moving part in a spherical motor pump is a spherically shaped rotor/impeller unit, which is seated on an ultra-hard, wear-resistant ceramic ball.
