Pump Top Watercool HEATKILLER DDC tapa de bomba X3 — Watercool, MPN 31017

Watercool HEATKILLER DDC Pumpenaufsatz X3 is a pump top designed for DDC-series pumps for custom liquid cooling loops. Manufactured by Watercool, this pump top replaces or upgrades the original top to provide a compact, serviceable interface between the pump housing and external fittings. The design focuses on compatibility with standard G1/4" fittings and secure mounting to typical DDC pump housings, enabling straightforward integration into PC cooling assemblies and bespoke radiator/pump configurations.

Advantages

The pump top offers reliable mechanical compatibility with DDC pump housings while maintaining low hydraulic restriction for efficient coolant flow. Machined contact surfaces and standardized inlet/outlet threads simplify installation and reduce the need for adapter parts. Its compact form factor saves space in confined cases and supports stable mounting to minimize vibration transfer. Materials and finish are selected to be corrosion-resistant in typical cooling fluids.

Suitable for

• Custom PC liquid cooling loops using DDC-series pumps
• Replacement of worn or damaged pump tops on compatible pumps
• Upgrading pump interfaces to accommodate different tubing or fitting layouts
• Small-form-factor builds where compact pump mounting is required

Key specifications

• Compatibility: designed for DDC-series pump housings
• Fitting interface: standard G1/4" threaded ports for inlet and outlet connections
• Mounting: compatible with typical DDC pump mounting points and brackets
• Material characteristics: corrosion-resistant finish suitable for common coolant types
• Form factor: compact top profile to reduce overall pump assembly height

How to use

Turn off and drain the cooling loop before removing the original pump top. Unscrew the existing top from the DDC pump housing following the pump manufacturer's service instructions, then clean the sealing surfaces. Fit the HEATKILLER DDC Pumpenaufsatz X3 onto the pump housing, ensuring correct orientation of inlet and outlet ports. Apply appropriate thread sealant or O-rings where specified, tighten fittings to the recommended torque, and refill and bleed the loop according to standard procedures. Verify there are no leaks and that the pump and loop operate within normal temperature and flow parameters.

Recommendations

Use compatible G1/4" fittings and quality tubing to maintain leak-free connections. Avoid mixing incompatible coolant chemistries and follow manufacturer guidance for mounting torque and seal replacement intervals to ensure long-term reliability.
