Brass body and flow
The top starts from solid brass, which is then hand-polished and dark nickel-plated. Aquacomputer says optimal flow behavior was observed during the development of the ULTITOP D5. The result it reports is an extremely quiet and smooth operation.
Mounting and decoupling
A fastening ring made of anodized aluminum and a suitable seal hold the pump. The bracket's silicone decouplers were specially developed for the ULTITOP, and the design effectively prevents the transfer of vibrations to the computer housing. Stainless steel sheets with M3 threads are inserted into the decouplers for easy assembly. The bracket can be detached by loosening a single screw, to ensure easy access to the pump. On a D5 NEXT, take the controller unit off before fitting the ring and re-attach it afterwards.
What the loop needs
The return line connects to the central connector, engraved "IN", the other line to the lateral one: two G1/4 fittings. The central thread sits in a recess 22 mm across and 3 mm deep, so wider connectors need suitable extensions (not included). The same top in acetal is the ULTITOP pump top (41123).
