Pump top Singularity Protium 2.0 D5 Pump Top Acetal SC-P2-D5T-AL for D5 pump housings

The Singularity Protium 2.0 D5 Pump Top Acetal (for D5 pump housings) is a precision-machined pump top engineered to interface directly with D5-series water-cooling pumps. Constructed from acetal, the pump top provides secure mounting and reliable fluid routing for custom liquid-cooling loops in desktop PCs. Its dimensions and port layout are optimized for straightforward integration into high-performance cooling systems and allow clean, leak-resistant connections to tubing and fittings.

Advantages

The acetal construction delivers good mechanical stability and chemical resistance appropriate for typical coolant mixtures used in PC water cooling. Precision machining ensures accurate alignment with D5 pump housings, reducing the risk of stress on seals and fittings. The design supports tidy loop layout and minimizes flow disruption by providing direct, unobstructed coolant paths. Lightweight material and tight tolerances simplify assembly and help maintain consistent contact with the pump housing.

Suitable for

• Custom PC water-cooling loops that use D5-series pumps
• System builders installing or upgrading high-performance cooling
• Enthusiasts seeking a reliable, machined pump top for clean loop routing
• Maintenance or replacement of existing D5 pump tops in desktop setups

Key specifications

• Material: Acetal (high-strength thermoplastic)
• Compatibility: Designed for D5-series pump housings
• Mounting: Direct interface for secure attachment to D5 pumps
• Fluid path: Direct routing suitable for standard fittings and tubing
• Finish: Precision-machined surface for tight tolerances

How to use

Before installation, verify pump housing compatibility and inspect seals and O-rings for wear. Mount the pump top onto the D5 pump housing following the pump manufacturer’s recommended torque values for fasteners to avoid deformation. Connect tubing and fittings to the pump top ports, ensuring appropriate sealing with thread tape or compatible O-rings where required. After assembly, perform a leak test with the loop filled and the pump running at low speed before powering the full system.

Recommendations

Use coolant fluids and additives that are compatible with acetal and approved for PC water cooling. Avoid aggressive solvents or cleaners that can degrade the material. Periodically check fittings and seals for tightness and replace O-rings if signs of aging appear. When tightening fittings, use manufacturer-recommended torque or hand-tighten with care to prevent cracking the pump top or damaging threads.
