Hydrogen Circulation Pump DQ30 – key features

  • Ideal explosion-proof capability
  • Avoid leakage with sealed lips
  • The rotor structure of the new line and tooth curve all meet the conjugate relation, no sharp point on the profile, the use of bilateral profile, rotor diameter adjustment is convenient, torque distribution between the rotor is reasonable, and small vibration.
  • The high radius and tooth top height are well designed to increase the area utilization coefficient and the gas transmission.
  • The active and driven rotors have equal diameters, good rotor stiffness, and high bearing capacity.
  • The pump shell, motor shell, and pump end cover are made of aluminum alloy with a hard anodized surface to improve corrosion resistance and reach a lighter weight.
  • Adopt synchronous gear drive to increase transmission efficiency
  • No oil operation to ensure environmental safety
  • Cantilever design, a small number of parts, low cost
