Application
Energy Storage Thermal Management System
This pump is designed for coolant circulation in energy storage thermal management loops. Its rated flow of 1900 L/min and head over 77 m support large-volume heat transfer. Broad temperature and pressure operating range accommodates outdoor and containerized energy storage environmental fluctuation.

Main Points & Industry Demands
Energy storage thermal management systems require continuous coolant circulation to maintain uniform battery temperature within safe limits. The system requires zero external fluid leakage to protect battery modules and electrical components. System designers seek pumps with high hydraulic efficiency and low noise output, able to operate reliably under wide ambient and coolant temperature variation. Material compatibility with copper piping is required, alongside long mechanical service life under variable working pressure. Compact dimensions help simplify container layout in energy storage cabinets.
Product Advantages as Core Solutions
The canned centrifugal pump structure removes dynamic sealing points, eliminating external leakage risk for battery cooling circuits. The brushless permanent magnet synchronous motor reduces footprint and power consumption for space-limited storage container installation. Closed twisted impeller realizes high flow capacity, improved hydraulic efficiency and reduced operating noise. High-life friction pair materials are adopted for the shaft assembly to sustain stable long-term operation. CF3M, PPS-GF40 and ceramic wetted parts provide chemical compatibility with copper pipelines and mitigate corrosion inside the thermal management loop.
Operational Mechanism
This wet rotor canned pump uses a permanent magnet rotor immersed directly in coolant. Magnetic field from the stator drives rotor rotation. The closed twisted impeller accelerates the working fluid and converts mechanical energy into hydraulic energy to circulate coolant through the energy storage thermal management circuit. No dynamic shaft seal separates the motor chamber from fluid passage, which removes potential leakage paths.
Selection Guide
Industry empirical practice references 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 as reference. This correlation serves only as empirical guidance for thermal management system sizing. Total loop pressure loss and actual operating flow should be calculated to confirm final configuration.
