The Multi PD Pump is designed for handling either fine or coarse fly ash from ESPs or from bag filters and can be used to convey directly to the main silos without using an intermediate hopper. There can be up to 8 pumps connected on the same pipeline with an ESP. The most efficient arrangement is for the vessels to be connected across the gas stream of the ESP so that each vessel receives approximately an even loading. No level probe is required in the ESP when using the Multi PD pump system.

The Multi-PD pump system is able to convey distances up to 750m (2460 ft) and at higher conveying velocities than with multi Dense Phase vessels. The Multi-PD system also has lower specific air consumption and utilizes smaller pipe sizes to achieve the same conveying rate as a multi Dense Phase system.

Standard Fabrication

The Multi PD pump assemblies are supplied complete with the original Dome Valve, electro-pneumatic controls and air supply piping, strainer, pressure regulation and control equipment pre-piped and pre-wired ready for connection to instrument air, power supply and connection to a suitable vent pipeline.

  • Vessels can be manufactured to most international pressure vessel codes designed for a working pressure of 7 barg standard. Special designs are available on request.
  • Vessels are free standing, special foundations are not required.
  • Optional isolating valve and adapter are shown for reference only.
  • Final working dimensions to be confirmed by certified drawings.
