Hydrogen Circulation Pump DQ47 - key features

High impeller area utilization coefficient and good dynamic balance.

With hard exhaust characteristics of forced air, when the pressure changes, the flow rate changes little.

The rotor meshing curve is an advanced compound line, with good sealing, less leakage, and volume efficiency is further increased.

Conveying medium does not contain oil.

Double row roller bearing, long service life.

Cantilever design, low number of parts, and cost controlling well.

The pump shell, motor shell, and pump end cover are made of aluminum alloy with a hard anodized surface to improve corrosion resistance.

The impeller surface is plastic-coated, with corrosion resistance, wear resistance, small clearance, and high efficiency.

Gear surface special treatment, high strength, good wear resistance.

The master-slave moving shaft is made of stainless steel whose properties are adjusted by quenching and tempering. It has high hardness and good mechanical properties.
