The heart of any liquid cooling loop is the pump — and when the loop grows beyond a single PC, pump performance stops being a spec-sheet detail and becomes the difference between a system that cools and one that struggles. The OCOCOO OC-D700 water cooling pump is engineered for exactly those demanding loops: high-capacity flow, high static head, quiet operation, and the control flexibility modern systems need.
Most water cooling pumps balance flow against head, sacrificing one for the other. The OC-D700 refuses the trade-off: with a maximum flow of 1,500 L per hour and a maximum head of 13 meters, it moves serious coolant volume through complex loops — multiple radiators, long tubing runs, CPU and GPU blocks in series, or external cooling towers — without the flow decay that cripples smaller pumps when resistance climbs. For builders scaling up to large external radiators or rack-style configurations, that combination means every component in the loop gets the coolant it needs.
At the core of the OC-D700 is a three-phase brushless DC motor — the same motor architecture trusted in premium pumps for its efficiency, longevity, and smooth operation. Rated life reaches 30,000 hours, and noise stays at or below 35 dB, keeping even powerful loops unobtrusive in living spaces and offices alike.
PWM speed regulation gives you full command of the pump from your controller or motherboard: dial flow down for silent idle operation, and ramp it up under load when every degree of cooling matters. The wide 8–13 V operating range adds another layer of compatibility across different controllers and power sources.
The OC-D700 is built for reliability and ease of use. The housing combines PPS and aluminum for structural strength and heat resistance with an acrylic reservoir that makes coolant flow and level visibly observable at a glance — no disassembly required to check that the loop is circulating. An internal buffer plate steadies flow and helps reduce turbulence and vibration.
Threaded G1/2 inlet and outlet ports connect directly to standard fittings, simplifying integration into existing loops. The pump runs on DC 12 V with large 4-pin power and small 4-pin speed-control connectors, keeping wiring straightforward in any build.
Every OC-D700 leaves the factory 100% pressure tested, with air-tightness verified to ≤ 0.2 MPa — the leak discipline that matters when a failure means draining the whole loop. OCOCOO's quality system is ISO 9001 certified and verified by TÜV Rheinland, backed by more than 30 national patents, a dedicated R&D team using CFD simulation and thermal modeling, and a monthly manufacturing capacity of 50,000 units. Whether you need one pump or a thousand, batch consistency is guaranteed.
High-performance PC builds: large custom loops with multiple radiators and water blocks. External cooling setups: external radiators and towers where long tubing runs demand high head. Server and industrial applications: compact, reliable coolant circulation for continuous-duty thermal management.
If your loop has outgrown ordinary pumps — or you are building a system where flow, head, silence, and longevity all matter — the OC-D700 delivers the performance headroom to cool it properly. Contact the OCOCOO team today for specifications, samples, and wholesale pricing for your project.
