Watercool PUM Watercool WCP D5

ultra-hard ceramic bearing ball. There is no conventional shaft bearing with bearing bushes. Due to the design, bearing play and thus an increase in operating noise is not possible. The pump remains low-noise over the entire running time. The self-adjusting bearing is lubricated and cooled directly by the pumped medium (wet-running pump). Separate maintenance is not necessary. All parts in contact with the medium are corrosion-resistant. Due to the spherical motor principle, it is not possible for the pump to block under normal circumstances. Even after a longer standstill, the pump starts reliably. The permanent magnet motor technology ensures a very high efficiency of the pump. The speed of the pump can be continuously adjusted over a wide range by means of a speed regulator built into the stator. This can be used to set a desired hydraulic output, but also to limit the electrical power consumption. The pump always starts with the same torque, regardless of the set speed, so that a reliable start-up is guaranteed even at the lowest power level. The pump is delivered without attachments. A suitable pump cover (e.g. HEATKILLER?? D5-TOP) is required for operation. This is available separately. The electrical connection is made via a 4-pin Molex socket. For speed monitoring the pump supplies a tacho signal via a 3Pin Molex connector.
