Application

ICT Cooling

This pump serves as the coolant circulation unit for ICT liquid cooling systems. Its rated flow of 1900 L/min and head exceeding 77 m support large heat transfer for high-density server racks. The wide temperature and pressure operating range enables stable operation within data center liquid cooling circuits.

Main Points & Industry Demands

ICT cooling systems require stable coolant circulation to dissipate high heat flux generated by computing hardware. External liquid leakage must be avoided to prevent damage to sensitive electronic components. System designers require pumps with high hydraulic efficiency and low acoustic emission, capable of operating under wide ambient and fluid temperature ranges. Wetted material compatibility with copper piping is necessary to suppress corrosion in cooling loops. Long service life and compact mechanical layout are also preferred for data center cabinet integration.

Product Advantages as Core Solutions

The canned centrifugal pump design eliminates dynamic sealing interfaces, removing external leakage risk for ICT cooling circuits. The brushless permanent magnet synchronous motor reduces overall size and power consumption, fitting space-constrained data center installations. Closed twisted impeller delivers high flow capacity, improved hydraulic efficiency and reduced running noise. High-endurance friction pair materials are applied on the shaft assembly to maintain long-term operational stability. CF3M, PPS-GF40 and ceramic wetted components offer chemical compatibility with copper pipelines and reduce corrosion risk inside the cooling loop.

Operational Mechanism

The permanent magnet motor drives the pump shaft and closed twisted impeller. Rotating impeller transfers mechanical energy to the coolant, raising fluid pressure and velocity to drive circulation inside the ICT cooling loop. With canned construction, no dynamic shaft seal is exposed outside the fluid chamber, which cuts off potential leakage paths between the fluid and electronics.

Selection Guide

Industry empirical practice uses 1.5 L/min flow corresponding to 1 kW heat load. With rated flow of 1900 L/min, this pump can support approximately 1267 kW heat dissipation for reference. This correlation is only empirical guidance for ICT cooling system sizing. Total pipeline pressure loss and actual operating flow should be calculated for final system configuration confirmation.
