Peristaltic Hose Pumps | Global Pumps

Verderflex Peristaltic Hose Pumps

Peristaltic hose pumps are ideal for transferring liquids with a high particulate content (up to 80%), viscous fluids and abrasive slurries. These pumps ensure precise dosing and accurate metering, making them a top choice for industries such as mining, chemical processing, food processing, printing and packaging, water treatment, and waste management.

Peristaltic pumps are available in a range of models, including the Dura Series and VF Series peristaltic hose pumps, as well as the Ds500, Vantage, and Rapide Series peristaltic tube pumps, designed for various applications.

Key advantages of peristaltic hose pumps:

High precision dosing: Accurate and repeatable performance, ideal for metering and chemical dosing
Energy efficient: Reduces operational costs while maintaining reliable performance
Minimal maintenance: Only the hose and lubrication require replacement
Chemical compatibility: Suitable for corrosive and abrasive materials
High suction capability: Effectively handles fluids with high specific gravity, entrained gas, or suspended particles
No operator intervention required: Reduces downtime and operator errors

WORKING PRINCIPLE OF PERISTALTIC PUMPS

Peristaltic pumps, a type of positive displacement pump, operate using the principle of peristalsis. The fluid is contained entirely within a flexible hose inside the pump casing, ensuring safe and efficient transfer.

Operation: Alternating compressions along the flexible hose draw fluid into the pump and propel it forward..
Sealing and propulsion: A rotating roller compresses the hose, forming a seal between the suction and discharge sides, preventing backflow. This seal moves along the hose, pushing the fluid towards the discharge line.
Priming: As the hose recovers its shape, a vacuum is created, drawing fluid into the pump .

This design ensures precise fluid transfer without contact between the fluid and mechanical components, making it ideal for abrasive, corrosive, or sensitive fluids.

APPLICATIONS

Peristaltic hose pumps are versatile and suited to a wide range of applications:

Abrasive fluids: Lime mixing, kieselguhr, circulation or dosing.
Corrosive fluids: Ferric chloride, copper sulphate and similar activators, process chemicals, acids – including alkalis.
Shear sensitive fluids: Coagulants, flocculants and bacterial remediation treatments
Mining industry: Dosing process reagents, transferring thickener underflow, handling polymers, and slurry transfer.
Water treatment: Dosing lime, hypochlorite, silicate, polymers, ferric chloride, as well as transferring sludge and filter press feeds.
Chemical industry: Capable of pumping corrosive acids, bases and hydrocarbons
Printing and packaging: Inks (including water-based inks), paints, dyes and glue.
Battery filling and chemical cleaning: Used for biocides, hydrogen peroxide, sodium hypochlorite, and caustic soda applications, as well as equipment sterilising and seed coating.
Laboratory systems: Biological broths and polluted stream processing
Agriculture: Suitable for dosing feed additives, animal vaccines and transferring waste materials.
Paper and pulp: Handles pulp and dye processing.
Food and beverage: Frequently used in breweries, diatomaceous earth processing, wineries, dairies, sugar refining, and abattoirs.

FAQs

Can peristaltic hose pumps run dry?

Yes, peristaltic hose pumps can run dry continuously without any damage, making them ideal for a range of challenging applications, including peristaltic transfer pumps and chemical dosing.

Are peristaltic hose pump reversible?

Yes, these pumps are reversible, allowing you to clear blockages in both the suction and discharge lines efficiently. This feature is particularly useful in peristaltic dosing pumps used for industrial or water treatment applications.

Can I use standard lubricating oil in the pump casing?

No, standard lubricating oil is not recommended as it can significantly reduce the life of the hose. For optimal performance and durability, we recommend using the Flex-Lube lubricant designed specifically for peristaltic hose pumps.

How long does the hose in a peristaltic pump last?

The lifespan of a hose varies per application, averaging approximately 2,000 hours. Factors influencing hose life include:

Type of product being pumped (e.g., abrasive or corrosive fluids)
Operating conditions (intermittent or continuous)
Suction and discharge pressure

This guide should be considered approximate, as actual hose life depends on specific operational factors.
