Engineered for High-Density Compute: Precision BLDC Pumps for AI & Data Center Liquid Cooling
Eliminate thermal throttling with 30,000h+ lifespan, leak-proof magnetic drive, and precise PWM control. Trusted by OEMs for Direct-to-Chip and Immersion Cooling.
AI's Heat Density Is Skyrocketing.
Is Your Cooling Strategy Obsolete?
With rack densities surpassing 20kW, traditional air cooling leads to throttling and hardware failure.
Extreme Heat Loads
Concentrated heat from GPUs overwhelms air convection, risking component lifespan.
Density Limitations
Air cooling forces you to space out servers, wasting valuable data center floor space.
Risk of Downtime
Thermal throttling leads to system instability and catastrophic downtime for critical AI tasks.
Rising Energy Costs
Fans consuming >20% of total power. PUE > 1.5 is no longer sustainable.

Optimized Fluid Dynamics for Closed-Loop Systems
With rack densities surpassing 20kW, traditional air cooling leads to throttling and hardware failure.
Pump - Features High Static Head (45M) to overcome micro-fin resistance. Zero-Leak Magnetic Drive ensures absolute reliability for AI clusters.
Water Tank - Buffers thermal expansion and removes air bubbles, ensuring a stable, maintenance-free hydraulic loop.
CPU/GPU - High-performance processors generating massive heat loads that require immediate, efficient thermal extraction.
Cold Plate - Dense micro-fins maximize surface area for heat transfer, efficiently absorbing heat from the chip above.
Radiator - Efficiently dissipates thermal loads into ambient air, returning cooled fluid to the reservoir to complete the cycle.
1
Overcoming Micro-Channel Resistance
Modern AI cold plates (CPU/GPU) use dense micro-fins that create high flow restriction. Our High Static Head (up to 45M) ensures sufficient flow rate even under high back-pressure.
2
Intelligent PWM Integration
Don't run at 100% all the time. The pump accepts PWM signals directly from the mainboard/BMS, dynamically adjusting speed based on real-time CPU thermal loads to save energy.
3
Zero-Leak Magnetic Drive
In a closed loop, seals are the weakest link. Our magnetic drive design eliminates the dynamic shaft seal, guaranteeing a leak-free operation for the server's entire lifecycle.
