DONDEL Product Upgrade — Fuel Cell Hydrogen Circulation Pump DQ60 II
The product launched this time is the upgraded version of the Fuel Cell Hydrogen Circulation Pump DQ60 — the DQ60 II. Both the motor and pump head have been upgraded, making it suitable for fuel cell systems with power ratings between 90 and 150 kW. Compared with the previous model, the DQ60 II has lower pressure sensitivity and higher flow rates in the high-pressure range, resulting in improved volumetric efficiency. Its power consumption is also reduced by up to 45% under the same operating conditions. The rotor has been optimized for higher durability and longer service life. The manufacturing and assembly processes have been refined to ensure greater product consistency. The optimized rotor design further enhances the lifespan of key components such as bearings.
