Overview

NBR for food hose elements

Suitable for a wide range of food products. Resistant to most cleaning chemicals. The hose element is critical to ensure pump performance, durability and efficiency. Bredel composite reinforced hoses are constructed from high-quality compounded rubbers reinforced with up to four individual layers of braided nylon, and finished by high-precision machining. Inner and outer layers are extruded and, after construction, machined to ensure critical tolerances are maintained.

Perfect 100 % compression eliminates slippage which can destroy shear sensitive product and reduce metering accuracy.

Examples of compatible media:

Fruit and fruit concentrates
Yoghurt and dairy products
Yeast, sugar, food additives
Resistant to various cleaning chemicals
