Details
The Aquacomputer D5 Pump Core (41091) is a D5 pump motor without a top, set by a built-in control knob and with a speed signal for monitoring. It just needs to be completed with a suitable enclosure, a D5 pump top or reservoir, before it can be used.
Properties
- Pump
- D5, electronically commutated spherical (ball) motor
- Speed setting
- Power selector dial or supply voltage
- Supply
- 8 - 24 V DC, 23 W at 12 V, 4 pin Molex plug
- Maximum head
- 3.7 m at 12 V
- Size
- 66 x 57 mm (diameter x height, without cables)
Motor and speed control
Aquacomputer calls the D5 body the basis for an extremely powerful pump. At its heart is an electronically commutated ball motor, which ensures quiet and smooth operation throughout the whole lifespan of the unit. Turning the integrated knob sets the pump speed, and hence the flow rate. As an alternative, the input voltage also controls the speed. Its electronic control board gives a reliable start up even at low speed settings.
For monitoring the pump's functionality, a speed signal is available on a separate 3 pin fan connector, so your fan header or controller can read it. Keep in mind that a valid speed signal cannot guarantee an actual flow of coolant. An overheat protection first reduces the pump speed when the temperature reaches a critical level. If it rises further, the pump shuts down completely and resumes operation automatically after cooling down.
What the loop needs
This motor runs only inside a housing, which is not included in delivery. That housing is a D5 top or reservoir, such as the ULTITOP pump top for D5 pumps (41123), the aqualis D5 pump top (41094) or another one from our D5 pump tops. Power comes from a standard 4 pin Molex plug on the PC's PSU.
Use Double Protect Ultra coolant or water. Coolants with solid micro particles must not be used: those in various non-transparent or opaque coolants damage the D5 pump bearing. During operation the rotor must point up or to the side in relation to the control knob, never down.

Notes
- The pump electronics are not water proof and must not get in contact with coolant; no submerged operation.
- Fill the system with coolant before starting the pump. To deaerate, sway the system gently or power the pump down and up several times until the rattling noises stop.
- The pump must not run dry for longer periods of time.
The installation manual for the Aqua Computer D5 covers mounting orientation, coolants, initial operation and the technical data.
