In this section, we would like to assist you with the selection of the appropriate conveying hose and suction hoses for the agricultural industry. In the following, we have compiled an initial selection of the most suitable hoses from our range for numerous applications in agriculture, whether for conveying seed or fertilizer, for irrigation and manure spreading, or for animal shed ventilation. In this product section you will find foodstuff hoses as well as antistatic and highly abrasive-resistant suction and discharge hoses. Our hoses also offer high resistance to chemicals, alkalis and acids as well as high ozone and UV resistance. For further information about our range of hoses for the agricultural industry see below.
Hoses for the agricultural industry
Applications and properties
If the hose is used for pneumatic grain conveyors or for the conveyance of seed and fertilizer, the abrasion resistance and also a long service life play an important role. We therefore recommend the AIRDUC® PUR 355 AS or AIRDUC® PUR 355 FOOD for these applications.
For the irrigation or spreading of insecticides and fertilizers as well as the use of barrel trailers for manure spreading and the like, we recommend the use of a full plastic hose such as the NORPLAST® PVC 379 GREEN SUPERELASTIC, the NORPLAST® PVC 388 SUPERELASTIC, NORPLAST® PVC 380 GREEN or the BARDUC® PVC 381 FOOD, as these are ideally suited for these applications due to their excellent resistance to alkalis, acids and chemicals.
For the ventilation of, for example, animal sheds, you can take advantage of the light and highly flexible polyurethane hoses PROTAPE® PUR 301 AS and PROTAPE® PUR 330 AS.
Hoses of the AIRDUC® PUR 351 FOOD and AIRDUC® PUR 355 FOOD series can be used for animal feed transport because they have a longer service life due to their high abrasion resistance.
Frequently asked questions
Which hoses are suitable for the conveying of seed and fertilizer?NORRES customers recommend the AIRDUC® PUR 355 AS, which is antistatic and has a high abrasion resistance.
Which hoses are suitable for use in seed drills?The AIRDUC® PUR 355 AS or alternatively the AIRDUC® PUR 355 FOOD can be used for this application.
Which hose allows a smooth transport of the conveyed material?All products listed in this category have been flow-optimized.
