Pump top Watercool HEATKILLER DDC Pumpenaufsatz X2 by Watercool (MPN 31016)

Watercool HEATKILLER DDC Pumpenaufsatz X2 by Watercool is a pump top accessory engineered for DDC-series water cooling pumps. It provides a standardized interface for fittings and tubing, enabling a compact and reliable connection between the pump and the rest of a custom PC liquid cooling loop. The design focuses on straightforward integration with common DDC pump housings and on organizing inlet and outlet routing to reduce stress on fittings and hoses.

Advantages

The pump top offers secure mechanical mounting and standardized fitting interfaces for easier installation and replacement. Its form factor helps minimize hose bending and supports tidy loop layouts. Materials and finish are chosen to be compatible with typical cooling fluids and to maintain leak-resistant connections when used with the recommended fittings. The accessory simplifies the transition from pump to tubing, which can reduce installation time and improve system reliability.

Suitable for

• Custom desktop PC liquid cooling loops using DDC-series pumps
• Systems where compact pump mounting and organized hose routing are required
• Upgrades or replacements of pump tops to improve fitting reliability

Key specifications

• Compatibility: DDC-series water cooling pumps
• Fitting interface: standard threaded ports for common compression fittings or barbed adapters
• Material: corrosion-resistant materials suitable for cooling fluids (metal and/or engineered plastics as manufactured)
• Mounting: designed for secure attachment to DDC pump housing with appropriate fasteners
• Flow orientation: defined inlet and outlet ports to simplify tubing routing

How to use

Mount the pump top onto a compatible DDC pump housing following the pump manufacturer's instructions and using the supplied or recommended fasteners. Attach fittings that match the pump top's threaded ports, tighten to the specified torque to avoid leaks, and connect tubing according to your loop layout, observing correct flow direction. After assembly, fill the loop with the appropriate coolant and perform a leak test at low pump speed before normal operation.

Recommendations

Use fittings and tubing compatible with the pump top's threading and recommended materials. Tighten fittings evenly and check for leaks after initial fill; avoid over-tightening metal fittings onto plastic threads. Periodically inspect connections during maintenance and use coolant formulations recommended for PC liquid cooling to prevent corrosion and deposits.
