Verderflex Hoses for Peristaltic pumps

Some industrial hose pumps in today’s market have machined exteriors, a process generally employed to achieve an equal wall thickness. In comparison, the unique Verderflex® production process is so precise that the exact wall thickness and outer diameter tolerances are maintained at each and every point. For this reason Verderflex® hoses do not have to undergo this additional process of external machining. When Verderflex® hoses are tested alongside their competitors, results indicate that there is no additional friction loss due to the wound surface. The textured surface actually creates micropockets of lubricant which promotes even lubrication coverage which results in longer hose life.

For corrosive applications requiring EPDM hose, Verderflex® recognizes the importance of a homogeneous material. Under normal wear, a hose will fail in the "cheeks" of the hose and form a leak path through to the outer layer. Some hose pump manufacturers simply use an EPDM inner core and supplement this with natural rubber in the cord and outer layers, which accelerates hose failure through these layers in corrosive applications. Verderflex® uses a homogenous EPDM material throughout the hose, which helps to extend hose life and protect the pump in these aggressive applications.

All Verderflex hoses have a coloured lettering on the exterior which indicates the type of hose. The Verderflex lettering is white for a NR hose, yellow for a NBR, red for a EPDM hose type, yellow with a white stripe for the Food Grade NBRF and green for Hypalon® or CSM.

• 12 standard hose sizes from 5mm (3/16") to 125mm (5").
• All are designed to maximise hose life by optimising the hoses’ fatigue strength.
• Hoses are available in Natural Rubber (NR), Nitrile Buna Rubber (NBR), EPDM (used with high temperature CIP solutions) and Hypalon.
• Hoses have colour coded identification tape bounded into the outer during manufacture to clearly identify material type.

WARNING
The information in these charts has been supplied to Verderflex by reputable sources and is to be used ONLY as a guide in selecting chemically compatible hose. It is important that the hose is tested with the chemicals under the specific conditions of the application.

Chemical compatibility refers to pure liquids for mixtures, further tests are required. Verderflex does not warrant (neither express nor implied) that the information in these charts is accurate or complete or that any material is suitable for any purpose.
