Aquacomputer ULTITOP Black Pump Top For D5 Pumps (41133)

The Aquacomputer ULTITOP Mirror Black Pump Top For D5 Pumps is an extremely compact top for one D5 pump, made of solid brass with G1/4 connection threads. Note: delivery is without pump and without connections.

Properties

• Pump: One D5 pump motor
• Material: Brass, hand-polished, dark nickel-plated
• Ports: G1/4, central IN plus one lateral
• Size: 72 x 72 x 34 mm, 72 x 86 x 44 mm with bracket/decouplers

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).
