Overview

APEX natural rubber (NR) hose elements

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 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.

Outstanding abrasion resistance. Generally resistant to diluted acids and alcohols.

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

Examples of compatible media:

Sludge with up to 85 % solids
Magnesium oxide and titanium dioxide
Water based paints, pigments
Food waste
