Hose Pump Hose | Watson Marlow Bredel
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 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.
Perfect 100% compression eliminates slippage which can destroy shear sensitive product and reduce metering accuracy.
Key features of Bredel hose elements include:
The key element in every Watson-Marlow Bredel hosepump is a superior composite reinforced hose. Constructed from high quality compounded rubbers, the hose is reinforced with four layers of braided nylon and finished by high precision machining. Since rubber cannot be over- or under- compressed, hose life and pump efficiency are both increased.
Watson-Marlow Bredel hoses offer:
The hose is available with four different liner materials to suit a wide range of chemical compatibilities:*
1. Natural rubber highly resilient with excellent abrasion resistance and mechanical strength. Resistant to dilute acids and alcohols. Liquid temperature range from -20° C (-5° F) to 80° C (175° F)
2. Hypalon Excellent chemical resistance, recommended for strong oxidizing products like concentrated acids, alkaline liquids and oxygen generating substances such as hydrogen peroxide temperature from 10° C (14° F) to 80° C (176° F) Note: Pump speed may be limited with hypalon hose
3. Buna N (NBR) FDA, USDA and 3A approved. Highly abrasion and wear resistant. Compatible with oils, fats, alkalines and detergents. Suitable for a wide range of food applications. Liquid temperature range from -10° C (20° F) to 80° C (175° F)
4. EPDM excellent chemical resistance, especially to concentrated acids, ketones and alcohols. Liquid tem perature range from -10° C (20° F) to 80° C (175° F)
*Consult Watson-Marlow Bredel technical services for details on operation up to 90° C (195° F). Please consult your Watson-Marlow/Bredel representative for further details on chemical compatibility.
