The GDS impeller is a hybrid gas dispersing impeller created by combining GDM and HWM-B impeller designs. Through its powerful radial and axial flow combination, it delivers superior gas distribution while preventing gas cavity formation. It provides homogeneous mixing and enhanced suspension performance under gassed conditions with low power consumption.
The GDS is a hybrid gas dispersing impeller manufactured by Mechanimix. Combining GDM and HWM-B designs, it operates across a diameter range of Ø200–1800 mm. Its radial and axial flow combination prevents gas cavity formation and delivers homogeneous mixing with low power consumption; preferred in the chemical, polymer and biotechnology industries.
The GDM+HWM-B combination produces powerful radial and axial flow, creating a dual flow pattern in a single impeller.
The radial flow component breaks up gas bubbles while the axial flow component distributes gas homogeneously throughout the tank.
Operates at low torque values thanks to the hybrid blade geometry, minimizing energy costs.
The specially designed blade profile prevents gas cavity formation under gassed conditions, maintaining mixing efficiency.
The axial flow component keeps solid particles in suspension even under gassed conditions, increasing reaction efficiency.
A single impeller meets both gas dispersion and suspension needs, reducing equipment and operating costs.
