Overview

F-NBR hose elements

The hose element is critical to ensure pump performance, durability and efficiency. Bredel composite reinforced hoses are constructed from high-quality compound rubbers reinforced with up to four individual layers of braided nylon, and finished by high-precision machining. White inner layer suitable for food contact. Outer layers are machined to ensure critical tolerances are maintained.

Suitable for most food products, including oils and greases. Meets FDA, EC and 3A standards.

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

Examples of compatible media:

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