The ULTITOP D5 is a very compact pump adapter for D5 pumps from aqua computer. It is made of very resistant acetal . During the development of the ULTITOP D5 , care was taken to ensure optimum flow behavior with this pump adapter . The mounting bracket provided with decouplers made of silicone prevents the transmission of vibrations to the housing. The result is a very quiet operation. The ULTITOP D5 is shipped from the factory with an anodized aluminum mounting ring and a matching gasket. A D5 pump is not included and must be purchased separately. Stainless steel plates with matching threads are inserted into the decouplers for assembly. With the help of a single screw, the bracket can be detached from the pump adapter. This ensures easy access to the pump. Note: A pump and the required connections are not included.
