Hose pump elements

EPDM hose

Overview

EPDM 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.

Excellent chemical resistance, especially to ketones, alcohols and concentrated acids.

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

Examples of compatible media:

  • Sodium Hypochlorite/Bisulphate
  • Ferric Chloride
  • Hydrochloric Acid
