| Gentle low shear pumping | Reversible pumping | Reduced energy costs |
| Avoids creating bubbles in inks and colourants | One pumps can feed the print head and recover inks at the end of a batch | Zero air requirement eliminates air costs and compressor maintenance charges |
Applications
Print and packaging customers have ever increasing quality demands : producers must avoid rejected batches because of bubbles whilst economic demands pressurise operating costs - Verderflex pumps can help improve operational performance
Pumping Urea
Process: during the recycled paper production process, many chemical compounds are added including 10-15% concentration Urea dosed at a pressure of 4 bar with a variable flow rate up to 50 l/h.
Paint Pigments
Process: VF65 pumps paint pigment to a filter press. The paint is pressed to produce a powder which is lighter and cheaper to ship. This pump is used without a frequency inverter and always runs at full speed controlled by a timer.
Pumping Resins in Laminate Manufacturing
The world’s demand for laminated furniture, worktops and flooring continues to grow with increasing demand for toughened surfaces leading to greater use of an abrasive resistant paper (ARP) coated surface. Traditional pumping solutions experience high rates of abrasive seal wear and require increased maintenance - problems not experienced with a Verderflex Rollit. Typically, the abrasion resistant surface is produced by adding Corundum (Al2O3 )to melamine resin to form a final product surface with enhanced ability to meet the anti-scratch Martindale test.
Pumping Glue with Peristaltic Pumps
A Packaging company in Australia needed an effective means to transfer glue at 6 l/min from its IBC holding tanks to its glue rollers. A flow rate of 6 liters per minute was required. The company initially contacted us with the suggestion that a lobe pump would best suit the job.
Industrial OEM Pump in paper packaging
A leading pan European paper packaging organisation, has opted for Verderflex industrial peristaltic pumps at its Scottish production facility.
Peristaltic Hose pumps in the paper industry
Even for the demanding pump applications of the paper manufacturing process, the high quality and reliable industrial hose pump series from Verderflex offers individual solutions with reduced maintenance costs and long service life.
Using Industrial Tube Pumps on Printing Presses
Across Europe we have successfully installed many Rapide R6 & Rapide R8 industrial tube Pumps into printing press industries.
Peristaltic Pump solves ink transfer problem
Peterson Packaging based in Denmark had been experiencing problems transferring ink from storage containers to the rollers on the print machine. The air diaphragm pumps that were currently being used were unable to transfer the water based ink gently enough and this led to bubbles forming in the ink which were then transferred to the finished product. Ruining the packaging and causing waste and added expense.
Pumps for the printing and packaging industry
Verderflex peristaltic pumps are manufactured in the EU within ISO 9001, ISO 14001 and ISO 45001 accredited facilities.
Verderflex® Dura
The Verderflex Dura is a true 2nd generation pump : the first real advance in hose pump technology since the high pressure hose. It combines a close coupled pump's compactness with the traditional long coupled pump's benefits and gains from a total re-design rather than adapting an original concept.
| Max flow | 33000 l/h |
| Max pressure | 16 bar |
Verderflex® Rapide
The Verderflex Rapide range of Industrial tube pumps are compact, simple to operate low pressure peristaltic pumps. Models are simple by design, can accommodate multiple pumping heads and have fast tool-less tube changeovers
| Max flow | 1020 l/h |
| Max pressure | 2 bar |
Verderflex® Rollit
Lubricant-free peristaltic hose pumps. The Verderflex Rollit is a family of lubricant-free, easy to maintain, low to medium pressure hose pumps. Rollits are available as 2 bar, 4 bar or 2 bar Hygienic versions with single or twin head styles.
| Max flow | 24500 l/h |
| Max pressure | 4 bar |
Verderflex® VF
The original Verderflex peristaltic hose pump series is now solely focussed on high flow applications and includes the widely used VF125, the world's largest high pressure hose pump.
| Max flow | 90 m3/h |
| Max pressure | 16 bar |
Verderflex Vantage 3000 and Smart tube pumps can to be used as standalone pumps, providing extremely accurate dosing with high repeatability on flow rates from a few millilitres per minute up to 17 litres per minute.
Alternatively the Verderflex OEM and Industrial Hose and Tube ranges offer custom designed tube pumps that can be integrated into 3rd party machinery.
The smooth flow of a peristaltic pump is perfect for pumping the shear sensitive inks, coatings and adhesives that are prevalent in this industry, without the foaming or separation that can be caused by centrifugal pumps.
A tube pump has no valves, seals or impellers that can become clogged eliminating downtime allied to no expensive parts. For a low ownership cost solution.
