The Clyde PD-Pump is a dense phase pneumatic conveying system designed for the efficient transfer of dust and other fluidisable bulk materials in heavy industrial applications.
Developed from the original Clyde Denseveyor technology, the PD-Pump is engineered to transport powders at high phase densities, ensuring efficient use of compressed air while maintaining low conveying velocities. This results in reduced pipeline wear, lower operating costs and highly reliable system performance.
The system incorporates the Clyde Dome Valve, uniquely actuated to maximise phase density during the discharge cycle, ensuring optimal conveying efficiency and reliable isolation under pressure.
PD-Pump systems are widely used across industries such as cement, minerals processing, power generation, and industrial processing, where dependable dense-phase conveying of fine powders is required.
The system is available in a wide range of vessel sizes and can be configured as single or multi-pump installations depending on capacity requirements.
According to the PD-Pump reference sheet, machines are available in sizes from 0.08 to 4.2 m³, delivering conveying capacities of 1–100 tph over typical distances of 200–800 metres, making the technology suitable for a wide range of industrial applications.
Key Features
