Eheim Pumps
Eheim built the pumps that the first generation of PC water cooling was based on, and plenty of loops still run them. The design comes from aquarium use, which is why they are quiet and rated for continuous duty measured in years rather than hours.
Stocked here: the Aquacomputer Aquastream Ultimate, the Eheim based pump with Aquacomputer's own electronics on top, giving speed control, flow and temperature sensing and aquabus connectivity rather than a bare 12V motor.
Adapter fittings to connect an Eheim to G1/4 hardware are in Eheim fittings. D5 and DDC pumps are in pumps.
