Laing DDC / Koolance PMP-400 DC Water Pump
This is now the best DC powered pump available for the computer watercooled industry in 3/8 OD.
The two best water pump manufactures LAING and DELPI badged under the Koolance name and come togeather to design a small quiet yet powerfull 3/8 OD
Water pump solution. This pump lasts longer, consumes less power and offers superior performance characteristics when compared to other pumps in its class.
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.
The PMP-400 is a high-pressure pump with a very low profile format.
