Verderflex Hose & Tube Materials Explained

Peristaltic pumps are widely used across industries because they can handle abrasive slurries, corrosive chemicals, viscous fluids, and shear-sensitive products with minimal maintenance and no seal failures. However, the performance and service life of a peristaltic pump relies heavily on selecting the correct hose or tube material for the application.

For industrial operations in mining, chemical processing, wastewater treatment, and manufacturing, hose material selection is especially important. The wrong material can lead to premature hose failure, chemical attack, reduced efficiency, and unnecessary downtime.

Verderflex® hoses and tubing are engineered specifically for demanding industrial environments, offering a range of material options designed to suit different fluid types, temperatures, and operating conditions. In addition, some Verderflex hoses are compatible with other peristaltic pump brands, making them a versatile replacement option for existing systems.

You can explore our full range of peristaltic pump tubing, along with our ranges of peristaltic hose pumps, tube pumps, and the complete Verderflex range.

Why Hose Material Matters in Peristaltic Pumps

Unlike many other pump technologies, the hose or tube in a peristaltic pump is the primary wear component and the only part that comes into contact with the pumped fluid. This makes material selection critical for:

• Chemical compatibility

• Abrasion resistance

• Hose life and fatigue strength

• Temperature resistance

• Food-grade compliance

• Suction performance

• Maintenance intervals

Verderflex hoses are designed with reinforced construction to maximise fatigue strength and extend operational life. Compared with many competitor hoses, Verderflex hoses contain additional reinforcements that help improve durability under continuous compression cycles.

The hose surface is also engineered with a textured finish that creates microscopic lubrication pockets. This promotes more even lubricant coverage, helping reduce friction and extend hose life without increasing operational resistance.

Additional design benefits include:

• Consistent wall thickness and outer diameter tolerances
• No requirement for external machining
• Reduced maintenance requirements
• Improved long-term reliability in demanding industrial applications

These hoses are available in 12 standard sizes ranging from 5 mm to 125 mm.

Understanding Verderflex Hose Materials 

NR (Natural Rubber)

Natural Rubber hoses are the most widely used material across industrial markets due to its excellent flexibility and fatigue resistance. It performs particularly well in abrasive and slurry applications where hose life is critical.

Its ability to repeatedly compress and recover makes it ideal for mining, wastewater, and heavy industrial pumping applications.

Common applications:

• Slurry transfer
• Lime dosing
• Wastewater treatment
• Abrasive chemical transfer

NBR (Nitrile Buna Rubber)

Nitrile Buna Rubber hoses are designed for fluids containing oils and fats. The material provides excellent resistance to petroleum-based products and oily wastewater streams while maintaining good durability under demanding operating conditions.

Common applications:

• Oily sludge transfer
• Industrial oils
• Fat and grease processing
• Waste oil systems

NBRF Food Grade Hose

NBRF combines the oil resistance benefits of nitrile rubber with an FDA and EC-approved food-grade liner. This makes it suitable for hygienic processing applications requiring compliance with food-contact standards.

Common applications:

• Food processing
• Beverage transfer
• Hygienic industrial applications

EPDM

EPDM hoses offer exceptional resistance to corrosive chemicals, particularly acids and oxidising agents. They are commonly selected for aggressive chemical dosing and industrial treatment processes.

Common applications:

• Acid transfer
• Chemical dosing
• Wastewater treatment
• Corrosive fluid handling

CSM - Hypalon

CSM is designed for highly corrosive and chemically aggressive applications where standard elastomers may degrade prematurely. It provides advanced chemical resistance and long-term reliability in harsh environments.

Common applications:

• Aggressive chemical transfer
• Industrial chemical processing
• Hazardous fluid handling

Verderprene Tubing

Verderprene is the standard option for many peristaltic pump tubes. This cream-coloured tubing is popular due to its versatility, durability, and FDA & USP compliance.

It is well suited to:

• General industrial dosing
• Water treatment
• Chemical transfer
• Low-pressure fluid handling

Platinum Cured Silicone Tubing

Platinum cured silicone tubing is designed for higher purity applications where low residuals and clean fluid handling are important.

Its translucent and odourless properties make it suitable for applications requiring hygienic fluid transfer.

Hose Compatibility with Other Peristaltic Pump Brands

Some Verderflex hoses are also compatible with other peristaltic pump brands, providing operators with a high-quality replacement option without requiring complete system replacement.

This compatibility can help:

• Reduce downtime
• Improve hose life
• Simplify maintenance planning
• Provide access to high-performance hose materials

When selecting a replacement hose, it is important to confirm dimensional compatibility, operating pressure, and chemical suitability for the application.

Choosing the Right Hose Material

Selecting the correct hose or tube material depends on several operational factors, including:

• Fluid chemistry
• Abrasion levels
• Temperature
• Pressure requirements
• Food-grade compliance
• Expected hose life
• Maintenance intervals

Choosing the correct material can significantly improve pump performance, reduce maintenance costs, and extend hose life in demanding industrial environments.
