A pump solution for every application

Verderflex
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.

Verdermag
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
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
