Application
CDU-in row
This pump matches the fluid circulation requirement of in-row CDU liquid cooling units. Its 1900L/min rated flow and over 77m head support high-volume coolant delivery. Wide temperature and pressure tolerance ensures continuous operation inside rack row cooling loops.
Main Points & Industry Demands
In-row CDU liquid cooling systems require continuous, reliable coolant circulation to remove concentrated heat from IT hardware. The loop demands zero external leakage to prevent damage to electronic components. System designers need pumps with high hydraulic efficiency and low acoustic emission, capable of operating across broad ambient and fluid temperature ranges. Material compatibility with copper piping is also essential, together with robust mechanical endurance under fluctuating system pressure. Compact footprint is preferred for limited rack-side installation space.
Product Advantages as Core Solutions
The canned centrifugal structure eliminates shaft sealing points, removing external leakage risk for liquid cooling loops. Adopting brushless permanent magnet synchronous motor reduces overall size and power consumption, fitting space-restricted in-row CDU installation. Closed twisted impeller enables high flow capacity, improved hydraulic efficiency and reduced operational noise. High-life friction pair materials are used for shaft assembly to extend runtime stability. CF3M, PPS-GF40 and ceramic wetted components offer chemical compatibility with copper pipelines, preventing corrosion within cooling circuits.
Operational Mechanism
As a wet rotor canned pump, the permanent magnet rotor runs directly inside the coolant. The motor magnetic field drives rotor rotation, and the closed twisted impeller accelerates the liquid. Hydraulic energy is generated to push coolant through the CDU liquid cooling circuit. No dynamic shaft seal is fitted between motor chamber and fluid channel, which isolates the motor from external leakage pathways.
Selection Guide
The industry general reference uses 1.5 L/min flow corresponding to 1 kW heat dissipation. With rated flow of 1900 L/min, this pump can support a heat load around 1267 kW as a reference. This correlation serves only as empirical guidance for CDU liquid cooling system sizing, and system pressure loss and actual working flow should be calculated for final configuration.
FAQ
Q1: What is the warranty period of this canned pump? A1: The product comes with a two-year warranty.
Q2: Is custom service available for this pump model? A2: Customization is supported according to customer requirements.
Q3: How long is the standard lead time after order confirmation? A3: Standard lead time is 20 working days.
