Hose pump elements

APEX NR hose


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
