Pump hoses and lubricants are vital for peristaltic pumps, ensuring efficient fluid transfer. Pump hoses, made from layers including an inner layer of materials like CSM, EPDM, NBR, NBR-FDA, and NR, withstand continuous compression cycles and handle various media. Lubricants reduce friction between the hose and pump's compression elements, minimizing wear, controlling temperature, and extending hose life. Lubrication is only required on peristaltic pumps with show technology. Roller technology doesnt cause the same amount of friction on the hose and therefore lubrication is not needed. High-performance lubricants ensure smooth operation and reduce maintenance. Together, high-quality pump hoses and lubricants ensure reliable fluid transfer, lower operational costs, and enhanced durability in industrial settings.

Peristaltic pumps, also known as hose pumps, are widely used in various industries for their ability to handle a diverse range of fluids, including viscous, abrasive, and chemically aggressive media. The core components of these pumps are the pump hoses and the lubricants that ensure their efficient operation and longevity.
How is a Pump Hose Constructed?
Pump hoses are composed of multiple components made from a variety of materials. The combination of the inner layer, pressure carrier, and outer layer ensures the conveying and dosing properties in continuous operation as well as the extended lifespan of the hose.
Outer Layer
The outer layer of pump hoses is crafted from an abrasion-resistant natural rubber (NR) compound, specifically engineered for industrial peristaltic pumps that utilize shoe and roller compression mechanisms. This layer is crucial for protecting the hose from external wear and tear, ensuring durability and longevity even under harsh operating conditions. The outer layer can be customized with either a rough or smooth surface, depending on the specific application requirements. A rough surface may provide additional grip and resistance to external abrasions, while a smooth surface can facilitate easier cleaning and maintenance, making it suitable for hygienic applications.
Pressure Carrier
The pressure carrier is a critical component that provides the hose with the necessary structural integrity and stability. It is constructed by weaving synthetic yarns into a robust nylon microfabric, called coardings. This intricate weaving process results in a highly durable fabric that can withstand significant mechanical stresses. By incorporating multiple layers of this fabric, precision hoses can achieve exceptionally high restoring forces and conveying pressures, capable of handling up to 16 bar. This multi-layered construction ensures that the hose maintains its shape and performance under high-pressure conditions, making it ideal for demanding industrial applications.
Inner Layer
The inner layer of the hose is the most critical component as it comes into direct contact with the conveyed medium. Therefore, it must meet stringent criteria based on the specific application. The inner layer is made from high-performance materials such as CSM, EPDM, NBR, NBR-FDA, and NR. Each material offers unique properties:
- CSM (Chlorosulfonated Polyethylene): Excellent resistance to chemicals, ozone, and UV light, making it suitable for aggressive chemical media.
- EPDM (Ethylene Propylene Diene Monomer): Good resistance to heat, ozone, and chemicals, ideal for water-based and non-oily fluids.
- NBR (Nitrile Butadiene Rubber): Superior resistance to oils and fuels, commonly used for oily and fatty media.
- NBR-FDA (a food-grade variant of NBR): Complies with FDA regulations, suitable for food and pharmaceutical applications.
- NR (Natural Rubber): High elasticity and abrasion resistance, suitable for general-purpose applications and solid-laden media. Has a 50% longer lifespan then any other hose meterial
The variety of materials ensures that the inner layer can safely and efficiently transfer a wide range of media, from hygienic and chemical to solid-laden fluids, enhancing the hose's versatility and performance in various industrial settings.

How can the lifespan of a pump hose be increased?
The lifespan of pump hoses depends on both the process parameters and the pump technology. It is recommended to reduce the rotor speed and adjust the conveying pressure to minimize hose abrasion caused by shoe or roller compression. The durability of the hose element can also be ensured by using shim plates and high-performance lubricants.
