Reservoir and Pump Kit BitsPower CR140 by BitsPower BPM-WTCR140 acrylic reservoir with pump mounting for custom PC water cooling

BitsPower CR140 is an acrylic reservoir and pump kit designed for custom PC water cooling loops. The unit combines a compact acrylic reservoir with a mounting area for a compatible pump, providing inlet and outlet ports and the mounting hardware required to integrate the assembly into multi-component liquid-cooling systems. The transparent acrylic body allows visual monitoring of coolant level and flow, while the combined reservoir/pump layout reduces the number of separate components in a custom loop.

Advantages

The reservoir and pump kit offers a space-efficient solution that integrates reservoir and pump mounting in a single component. Its acrylic construction provides clear visibility of coolant and easy detection of air bubbles or contaminants. Pre-positioned inlet and outlet ports simplify connection to existing tubing and fittings, and included mounting hardware helps achieve a secure installation in most custom PC cases or dedicated mounting locations.

Suitable for

• Custom PC liquid-cooling loops that require a combined reservoir and pump mounting option
• Small to medium-sized builds where space optimisation is required
• Systems where visual coolant monitoring and easy filling/bleeding are needed

Key specifications

• Material: transparent acrylic reservoir body designed for coolant visibility
• Integrated pump mounting area compatible with standard pump form factors
• Inlet and outlet ports for loop integration and standard fittings
• Includes mounting hardware for secure installation in PC cases or mounting brackets
• Function: combined fill/expansion reservoir and pump housing for liquid-cooling loops

How to use

Install the acrylic reservoir in a suitable location inside the case or on a mounting bracket where the pump and reservoir will be accessible for filling and maintenance. Mount a compatible pump to the designated pump mounting area and secure using the supplied hardware. Connect input and output tubing to the reservoir ports using appropriate fittings and ensure all connections are tightened. Fill the reservoir with compatible coolant, power the pump briefly to circulate and bleed air from the loop, and re-check connections and coolant level before regular operation.

Recommendations

Use coolant and fittings that are compatible with acrylic components and the pump you intend to mount. Perform initial leak testing and loop bleeding with short runs of the pump while the system is powered from an external source or with system components offline. Regularly inspect the reservoir for signs of discoloration, deposits, or leaks and top up coolant as needed to maintain proper loop performance.
