Danger Den / Laing - DDC-12V 

Center Inlet Version REV3.2 18W

This is now the best DC powered pump available for the computer watercooled industry. Get the brochure here.

Design Characteristics:

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:

• 1/2" Center Inlet and 3/8 " Outlet - 3/8" ID tubing can be used on the inlet with a little brute force.  Check out this movie.
  
• Motor design: Electronically commutated, brushless DC, spherical motor Voltage Range: 8 to 13.2 VDC
• 9 VDC required to start
• Motor rated at: 18W
• Quiet operations at ~31dBA
• 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
• 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.
