CDR pumps for the fertiliser industry

Applications

The fertiliser sector is mainly divided into two areas: “commodities” and “specialties”. The first area includes products derived from raw materials such as methane, used for the production of ammonia, urea, nitric acid, and ammonium nitrate, as well as from sulfuric acid and phosphate rocks, possibly combined with potassium salts. The fertilisers obtained can be either straight or compound and derive from synthesis or mixing processes, depending on the technology employed.

The second area concerns “specialties,” a category of fertilisers characterised by highly specific, differentiated performance. These products require advanced and cutting-edge technologies, as well as flexible production facilities capable of promptly responding to market demands.

In the fertiliser production industry, the most commonly used CDR centrifugal pumps are the UTS, UTN, XTN, XTS and UCL.

The UTS pump, made of AISI 316 stainless steel, is designed for continuous operation (24/7) and can handle wide temperature ranges, from -100°C to +300°C, thanks to specific configurations. The integral cast feet ensure optimal resistance to connection loads and precise alignment between the pump and motor.

The UTN pump is intended for continuous process duty and is particularly suitable in its PFA version, ensuring chemical compatibility with the fluids used in fertiliser production.

The new XTS and XTN centrifugal pumps were developed for pumping liquids containing suspended solids (slurries), a common condition in fertiliser production. A major advantage of these pumps, thanks to magnetic drive technology, is the absence of emissions. The X series was designed with innovative technologies to improve performance, safety, and reliability in basic chemical processes.

Finally, the UCL is a lined mechanical seal centrifugal pump, available with PFA, PVDF or polypropylene linings. UCL pumps are ideal for handling corrosive, hazardous, or dirty liquids, thanks to the lining that protects all parts in contact with the process fluid. The UCL can handle fluids up to 140°C with a PFA lining, up to 100°C with PVDF and up to 70°C with polypropylene. Furthermore, it is possible to choose between single or double mechanical seals, depending on the specific application requirements.
