china slurry pump for vapour blasting

The dredge pump is designed to draw sediment, debris and other hazardous materials from the surface layer into the suction pipe and transport the material through the pipe to the discharge site. The pump must be able to handle common solid debris of various sizes that can pass through the pump, thus minimizing the downtime required for cleaning.

Larger impellers made of more material. This is to compensate for the wear and tear caused by abrasive slurries.

Metal and/or rubber pump bushings are used to combat the erosion of solid particles found in the slurry. Metal slurry pump housings are usually made of carbide to resist erosion caused by increased pressure and circulation. Sometimes wear-resistant steel is used on the pump casing so that the pump can be welded if repairs are needed.

For example.

The first major requirement for >slurry pumps is to provide adequate service life. The erosive and corrosive effects of slurries, such as the impact of high velocity flow of liquid/solid mixtures, can be really challenging. In many applications, some of the solids in the mixture are larger than the particles normally specified; therefore, the pump should be able to pass through them without causing any damage or operational problems.

The terms flushing and quench, often seem to be confused or misused when discussing seal support schemes for , slurry pumps, . As the concepts of a mechanical seal cartridge and a filled seal cartridge are slightly different, I will discuss them separately and in turn.
