A range of Verderflex peristaltic pumps has helped a salt producer in Spain to enhance its process.

Although salt is the primary product, the raw material from which it is extracted also contains silica as well as mud and other minerals.

These sodium silicates are used for food preservations, water treatment, automotive engine repair and fire protection.

Once excavated from the hills surrounding the plant, the raw material is combined with water in a mixing vessel to dissolve the salt.

The combination of salt water, silica slurry and mud is transferred to a decanting system for separation, where a Verderflex VF65 hose pump is responsible for transferring the highly abrasive silica slurry to a storage tank.

Abrasion is not a limiting factor for Verderflex peristaltic pumps, mainly because they have no seals or valves that come into contact with the liquid being pumped.

The silica slurry is entirely contained within the natural rubber hose, which is designed to reduce fatigue and provide a long service life.

The hose is the only wearing part and is claimed to be quick and simple to replace, keeping downtime to a minimum.

Hoses in peristaltic pumps generally fail owing to fatigue between the rubber layers and the reinforcement.

However, the Verderflex production process ensures that the exact wall thickness and outer-diameter tolerances are maintained at every point without the need for exterior machining.

The textured surface of the hose creates micropockets of lubrication, promoting even lubricant coverage and further extending hose life.

Two further Verderflex pumps – a VF40 and a VF65 – are employed to transfer the mud slurry to a filter press for de-watering.

The salt water is then subjected to further filtration to remove more impurities.

After evaporation, crystallisation, granulation and forming, the salt emerges from the process line as extra-high-purity pellets.

A pump solution for every application

Peristaltic hose pumps are very versatile however generally they are for heavy-duty applications such as abrasive slurry, high solid content or high suction lift requirements found in industrial, sewage and mining applications. Our VF range features the world’s largest ID hose pump for the most demanding applications.

Advantages of Verderflex Peristaltic pumps:
✔ Ideal solution for pumping liquids and dosing chemicals
✔ Verder’s peristaltic pumps can pump abrasive, highly corrosive, viscous, high density and shear sensitive products.
✔ Verderflex® peristaltic pumps are used in many industries including: water and wastewater, mining, food & beverage, chemical, pharmaceuticals, and the oil and gas industry.

With the absence of mechanical seals, the Verdermag® range eliminates the danger of abrasive wear from the drive shaft and seal faces and instead uses an o-ring sealing system. As the pump has no vulnerability to containing the media, it can provide reliable handling of hazardous fluids such as volatile, corrosive and toxic chemicals with no risk to employees, the environment or surrounding equipment. The range encompasses compact low flow/head pumps commonly used in OEM systems through to high flow, heavy duty pumps rated up to 200 bar. For compatibility with all types of chemicals the range is available with both metallic and non-metallic materials such as ETFE and a range of alloys. Custom pump specifications are available.

Advantages of Verdermag centrifugal pumps:
✔ Low flow OEM systems such as circulation of acids and solvents
✔ Transfer of industrial chemicals such as CIP, Acids, Solvents
✔ Thermal oil circulation between -100oC and +200oC
✔ Circulation in high pressure systems such as nanofiltration of industrial effluent, desalination and fast-loop systems.

Verderhus screw centrifugal pumps combine the best features of centrifugal and positive displacement pumps to define a new standard for low head, high flow pumping. Verderhus® pumps transfer your product gently and efficiently. The open impeller allows large solids to be easily pumped that reduces the risk of cavitation, which can cause serious damage to a pump and to the production process. A Verderhus pump will lower both energy use and ownership costs.

Advantages of Verderhus screw channel pumps:
✔ Clog free operation, reliability for your process
✔ Highly efficient, low energy consumption
✔ Solids pumping up to 13% of the flow volume
✔ Low-shear, gentle pumping action, results in less damage to the product
✔ Minimal wear, even with abrasive fluids, longest life time
Typical application areas for Verderhus screw channel pumps
✔ Thick sludge in wastewater treatment
✔ Macerated food waste
✔ Sewage waste
✔ Circulation of lime chemical
✔ Paper pulp
✔ Mining
✔ Production of biogas
✔ Power stations
