Pumppu Alphacool DC-LT 2

The Alphacool DC-LT 2 2600rpm Ceramic - 12V DC (Sinus PCB) is a compact water-cooling pump intended for PC liquid cooling loops. Built with a ceramic axle and precision-balanced impeller, the pump offers an efficient design with low power consumption and a wide control range. Its true 3-phase sinusoidal control and high-precision ceramic bearings enable quiet operation, making it suitable for small to medium-sized loops and systems where low noise is a priority.

Advantages

The pump combines a three-phase sinusoidal control circuit with a ceramic axle and magnet-suspended impeller to minimize vibration and noise. Its mechanical efficiency results in lower power draw for comparable hydraulic performance. The unit starts reliably from a 7V supply and provides a broad speed control range up to 2600 rpm. The compact dimensions and durable plastic/ceramic construction simplify installation in tight cases and custom loops.

Suitable for (tasks / use cases)

• Small to medium-sized PC water-cooling loops
• Silent or low-noise workstation and home PC builds
• GPU-AiO and compact closed-loop solutions
• Systems requiring efficient, low-power pumps

How to use

Integrate the pump into your water-cooling loop following standard loop-order and mounting practices. Ensure the pump is mounted securely in a position that allows reliable feed of coolant to the inlet to avoid dry running. Connect the pump to a 12V DC supply or a controllable voltage source and set the voltage within the supported range; the pump reliably starts from 7V and can be modulated up to its 2600 rpm rating. Use appropriate fittings and tubing compatible with the pump housing to prevent leaks.

Recommendations

For low-noise operation, operate the pump with a sinusoidal three-phase controller or an appropriate DC fan/pump controller and maintain correct loop fill and bleed procedures. Regularly inspect connections and coolant condition to sustain quiet, efficient performance.
