Material
hose wall: polyester polyurethane (in comparison with polyether polyurethane more abrasion resistant, acc. to DIN 53516)
spiral: spring steel wire
DN 20 - DN 300
- special hose for extremely abrasive media
- transport hose for difficult materials, such as sand, gravel, grain
- transport hose for loading and extraction in glass works, mineral treatment, steel works, quarries, ship yards and docks, cement works
- any transport and loading equipment
- protection hose against mechanical pressure
- very high vacuum and pressure rating
- very close spiral
