In the ceramics industry, where abrasive slurries must be pumped at pressure, rapid pump wear is sometimes regarded as inevitable. But in the basic Hydra-Cell design (which is not reliant on seals to protect key components) the most vunerable points of attack are eliminated. Wetted parts exposed to abrasives are available in a range of resistant materials. Operating pressures can be as high as 70 bar.

For the most severe wear conditions the dedicated Hydra-Cell SD Series of slurry duty pumps is offered. Ideal for systems up to 17 bar, it features a non-metallic head and unique valve design in a combination of materials.

The Hydra-Cell is a very different type of pump from the AOD type of pump, which is commonly used in the industry for spraying glazes, coatings and ceramic mixes. Important advantages of the Hydra-Cell over AOD pumps include: a unique check valve design, significantly reducing maintenance costs; higher efficiency, enabling a saving in energy cost by as much as 85%; a multiple-diaphragm pump head, producing virtually pulseless flow – thereby giving more control over coating thickness, improving product quality and making more efficient use of materials.

Hydra-Cell process applications in the industry include production of tiles, ceramic components and spray drying of granules used in the moulding of tableware.
