The liquids pumped at high pressure in spray drying – a process used in many different industries for the production of powders – are as varied as the products produced. They may be corrosive, abrasive, non-lubricating or have other attributes that can create seal wear and maintenance issues for piston pumps and other types of pump with dynamic seals.

Hydra-Cell seal-less design eliminates seal maintenance. The pump has no difficulty handling aggressive or thin liquids, or liquids with particles. And its multiple-diaphragm head design enables it to deliver the smooth, virtually pulse-free high pressure flow that the application requires. A wide choice of materials means that material selection can be optimised for the process, and because its design is flexible the same pump can be optimised for a quite different liquid simply by changing the materials of the liquid end.

The pump can operate efficiently from very low speeds up to 1000 rpm and 1450 rpm, dependent on model.

Overall, a compact, cost efficient pump ideal for spray drying.
