Overview

CSM 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 resistance to strong, oxidizing products and concentrated acids and bases.

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

Examples of compatible media:

Hydrogen Peroxide up to 60 %
Cationic flocculant (polymer)
Highly concentrated Sulphuric Acid
