Pump housing Barrow LD5HK-V1 b POM Black — water-cooling pump housing

Barrow LD5HK-V1 b POM Black pump housing is a replacement and upgrade enclosure designed for compatible water-cooling pumps in custom PC liquid-cooling loops. Manufactured from POM (polyoxymethylene) plastic, this housing provides structural support for internal pump components, a mounting interface for installation, and defined channels to help route coolant and secure fittings. The black finish offers a neutral appearance suitable for a range of builds and modding projects where an OEM housing is being replaced or customized.

Advantages

The POM material offers high dimensional stability, low friction, and resistance to wear, which helps maintain reliable alignment and smooth operation of pump internals. The housing is shaped to facilitate straightforward mounting and secure sealing with standard pump parts and fittings. Its black color provides a discreet, uniform look inside a PC case and can simplify aesthetic coordination with other cooling components.

Suitable for

• Custom PC liquid-cooling loops where the original pump housing is replaced
• Maintenance tasks that require a spare or replacement pump enclosure
• Modding projects that change pump appearance or mounting configuration
• Systems that need a durable plastic housing with good mechanical tolerances

Key specifications

• Material: POM (polyoxymethylene) plastic
• Color: Black finish
• Function: Replacement/upgrade enclosure for compatible water-cooling pumps
• Compatibility: Designed for pumps matching the housing mounting and port layout
• Purpose: Provides structural support, mounting interface and coolant routing channels

How to use

Before installation, confirm that the pump’s mounting pattern and port locations match this housing. Remove the original housing following the pump manufacturer’s disassembly procedure, taking care to drain and dry the loop to avoid spills. Transfer internal pump components into the Barrow POM housing, ensuring seals and O-rings are correctly positioned and fittings are tightened to the manufacturer’s torque recommendations. Reinstall the assembled pump into the system, refill and bleed the loop according to standard liquid-cooling procedures, and verify there are no leaks and that the pump runs smoothly.

Recommendations

Use compatible sealing components and avoid overtightening fittings to prevent deformation of the plastic. Inspect O-rings and threads for wear during installation and replace them if necessary. Follow standard safety practices for handling coolant and electrical components, and perform a leak test at low system speed before normal operation.
