Micro Brushless DC Submersible Pump for Computer Water Cooling and USB Circulation

This micro brushless DC submersible pump is designed for reliable water circulation in compact applications such as computer water cooling loops, aquariums, humidifiers, and air conditioners. Its amphibious design allows fully submersible or dry installation, and with an IP68 rating it can operate completely immersed in water. A built-in filter helps prevent debris from blocking the inlet, reducing the need for frequent cleaning. The pump runs quietly at under 35 decibels and uses a permanent brushless magnetic rotor with a pure copper enameled wire coil for efficient, long-lasting performance. Power is supplied via a USB connection through a 5.5 x 2.1mm DC 12V female connector.

Features and Construction

The pump is built from PC and ABS materials and includes several design elements that improve reliability and ease of use in tight spaces. The motor and electronics are sealed with epoxy resin to protect against water ingress.

Material and Build

The pump body is made from PC and ABS plastic, a combination that offers rigidity and resistance to water exposure. The motor uses a permanent brushless magnetic rotor with pure copper enameled wire, which reduces internal heat generation and supports longer operational life. The circuit board and coil are encapsulated in epoxy resin to meet the IP68 waterproof standard.

Size and Practical Fit

The pump measures 60 x 49 x 45 mm (2.36 x 1.9 x 1.77 inches) and has an 8 mm inlet and outlet diameter. This compact footprint allows installation in tight spaces such as inside a computer case or small aquarium sump. Four rubber suction cups on the bottom can be pressed onto smooth surfaces to hold the pump in place and dampen vibration.

Uses and Placement

This pump is suitable for moving water or other non-corrosive liquids in small closed-loop systems. Its amphibious capability means it can be placed either fully submerged in water or externally with the inlet connected to a water line.

Event or Professional Use

For professional or hobbyist builders, this pump can be integrated into custom water-cooling loops for desktop computers or small-scale laboratory recirculation systems. The low noise level, under 35 decibels, makes it appropriate for noise-sensitive environments such as recording studios or office LAN setups.

Everyday Home Use

In the home, the pump can be used in tabletop water fountains, small humidifiers, or desktop aquariums where space is limited. The included filter helps keep the inlet clear of debris, which is useful when the pump is placed in water that may contain small particles.

Benefits and Buying Value

The pump combines low power consumption with durable construction, offering practical value for users who need a reliable circulation solution in compact spaces. Its brushless magnetic rotor reduces wear compared to brushed alternatives, and the epoxy-sealed electronics allow safe submersion.

Reuse and Low Maintenance

The permanent brushless design has fewer moving parts to wear out, which supports longer intervals between replacements. The included filter is easy to clean and helps maintain flow by preventing blockages. When used within the specified temperature range of 0 to 100 degrees Celsius, the pump can be transferred between different setups without issue.

Why Choose This Product

This pump offers specific capabilities in a small package: IP68 waterproof rating, very low noise, and a magnetic rotor that reduces energy loss. The rubber suction cups and filter add practical convenience that reduces setup time and maintenance effort. For anyone building a compact water circulation system, this pump provides a purpose-built component with clear specifications.
