Danger Den / Laing - DDC-12V REV3.1 12W

This is now the best DC powered pump available for the computer watercooled industry. Get the Brochure - It shows the differences between the 3.1 and 3.2.

Design Characteristics:

The pump electronically commutated wet rotor design results in only one moving part in the entire pump. A spherically suspended rotor/impeller rests on top of a ceramic ball and is driven magnetically, thereby eliminating the need for a shaft motor connection. The pump lasts longer, consumes less power and offers superior performance characteristics when compared to other pumps in its class.

Pump Technical Data:

DDC 3.1 runs a bit quieter (25dBA) than the DDC 3.2 due to motor speed/power.
Motor design: Electronically commutated, brushless DC, spherical motor Voltage Range: 8 to 13.2 VDC
9 VDC required to start
Motor rated at: 12W / 1.0 Amp
Maximum system pressure: 21.75psi, 150 kPa (1.5 bar)
Temperature range: Up to 140F (60C)
Acceptable media: Domestic hot water, water/Glycol mixtures and other media on request.
Corrosion resistant
50,000 MTBF
Warning: Do not run pump with out fluid.

Design Advantages:

50,000 hours mean time before failure (MTBF)
The pump is the smallest pump in its class and can fit into very confined operating spaces and virtually every desktop computer!
Maintenance is not necessary under normal conditions and even after lengthy shutdown periods a reliable start-up is virtually guaranteed.
The flow rate and performance characteristics can be easily controlled by voltage variation.
The rotor/impeller is suspended in the pumped fluid and the rotor is self-aligning so noise does not increase over time.
