APEX Buna N (NBR) hose elements

The hose element is critical to ensure pump performance, durability and efficiency. Bredel APEX composite reinforced machined hoses are constructed from high-quality compounded rubbers reinforced with several 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.

Resistant to oils, greases, alkalis and detergents.

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

Examples of compatible media:

Sludge with fractions of hydrocarbons
Polyaluminium chloride
