Watercool HEATKILLER D5 PWM (30060)

A D5 water-cooling pump with PWM speed control, delivered as the bare pump without a top, for a D5 pump top or a reservoir with a D5 option. The Watercool HEATKILLER D5 PWM (30060) connects through the 6-pin Watercool Pump Interface (WPI) and moves up to 1500 l/h.

Properties

• Pump: D5, PWM, without top
• Power: 6-pin WPI, 12 V DC nominal, max. 30 W
• Flow: Max. 1500 l/h, 3.7 m head at 12 V
• Size: 65 x 65 x 67 mm

The spherical motor principle

This DC pump works according to the spherical motor principle invented by Laing. Its only moving part is one spherically shaped unit, rotor and impeller in one, built around a permanent magnet. That unit is supported by a wear-resistant, ultra-hard ceramic bearing ball.

In this case there is no conventional shaft, no shaft seal and no bearing with bearing bushes. Due to the design, the development of bearing play is not possible, and thus no increase in operating noise follows from it. So the pump remains quiet and low-noise throughout its entire service life.

The bearing is self-adjusting: it is lubricated and cooled directly by the pumped medium (a wet rotor pump). Separate maintenance is not necessary, and all parts that come into contact with the medium are completely corrosion-resistant.

Due to the ball motor principle it is generally not possible for the pump to become blocked, and it starts up safely even after a long period of downtime. Watercool says the permanent magnet motor technology ensures that the pump is very efficient.

Speed controller in the stator

Using a speed controller integrated into the stator, the speed can be adjusted continuously over a wide range. It can be used to set a desired hydraulic output, but also to limit the electrical power consumption. Regardless of the set speed, the pump always starts with the same torque, which means reliable starting is guaranteed even at the lowest power level.

Watercool Pump Interface

The Watercool Pump Interface (WPI) is Watercool's central interface for connecting pumps. In addition to the supply voltages, the PWM, RPM and aRGB signals are transmitted via a single cable, and the cable routing is therefore compact and elegant. The electrical connection of this pump is made via the WPI: the speedometer (RPM) signal and PWM both run through its 6-pin connector.

What the loop needs

The pump is delivered without any attachments (the scope of delivery is the pump and a SATA cable), and one is required for operation. Watercool optimized it for the HEATKILLER TUBE and the MO-RA IV Tank. Pick a suitable pump attachment (e.g. the HEATKILLER® D5-TOP), or an expansion tank with a D5 option, for example the HEATKILLER Tube 100 D5 or the HEATKILLER Tank 200 D5.

Notes

• The pump can be used in every mounting orientation except with the rotor facing downward. The rotor is not fixed to the axle and could shift and rub against the housing.
• The coolant lubricates the bearing, so never run the pump dry.
• Watercool does not recommend water additives with suspended particles; they can clog the pump or wear the bearing.
• Watercool recommends demineralized or deionized (distilled) water with a suitable corrosion inhibitor as coolant.
