  • Verderflex Peristaltic Hose Pumps Industrial Applications

    1. 1. Verder Industrial Applications PAUL NELSEN MANAGING DIRECTOR
    2. 2. Introduction Verder, Inc. • Main stocking facility located in Macon, GA • Master Distributor for: – Alfa Laval / SSP Industrial Rotary Lobe Pumps – Verderflex Peristaltic Hose Pumps – Verderair Air Operated Diaphragm Pumps • Large stocking/Repair facility for all product lines
    3. 3. Who is Verder, Inc? – Part of the Verder Group, founded in 1959, international headquarters located in Holland – North American headquarters (warehouse, sales, & assembly) through Verder, Inc., Macon, GA – Offices located in 14 countries across the globe (UK, Netherlands, France, Germany, Belgium, Poland, China, Czech Republic, South Africa, Norway, Romania, Austria, Slovania) – 450+ direct employees worldwide, 60 in the US branch
    4. 4. Who is Verderflex? – Largest Peristaltic Pump Manufacturer in the world • Smallest size is 5mm ID • Largest size is 125mm (5”) ID – Leader in product innovation • Dura product line • Smart tubing pumps – Superior Hose life • Longest lasting in the industry • Color-coded for easy recognition
    5. 5. Principle of Operation •Slow speed rotor with 2-sliding shoes alternately compress and relax a rigid but flexible hose providing accurate and wear resistant operation
    6. 6. Application Keywords • Abrasion resistant – Hose life is not related to a product’s abrasive qualities – The hose fails due to fatigue or chemical action, not abrasion • Solids Handling – Able to pump liquids containing up to 80% fine inorganic solids (Slurry) – Up to 10% sludge capabilities • No moving parts in the liquid stream – No contamination of product, pump or gearbox – No metal to metal contact – Smooth liquid passage (no valves, dead corners, or mechanical parts)
    7. 7. Application Keywords II • Self priming / Dry Priming – Up to 95 % vacuum or 31’ lift of water • Dry-Running – The hose is lubricated from the outside – Able to pump air or products that “off-gas” (NaOCl, Yeast) • Reversible rotation – The pump can be used to empty lines or clear blockages • No internal backflow – Accurate Dosing (true positive displacement) – Rotary pinch valve – repeatability ± 1%
    8. 8. Application Keywords III • Shear sensitive products – Suitable for handling Flocculent/Coagulant, Polymers – Product is not damaged, Process Performance Improved • Easy maintenance – Low cost of ownership (hose is only wearing part) – Easy and completely cleanable without disassembly – Reduced down time (maintenance in place)
    9. 9. Dosing - The Key Advantages • Abrasion resistance • Suitable for handling shear sensitive products (floc) • Has no internal backflow giving accurate dosing - no slip - repeatability ± 1% - metering ± 5% • Able to pump liquids containing up to 80% inorganic solids and can also pump air or products that “gas”
    10. 10. Dosing Formats • There are 2 standard dosing styles • Fixed speed: constant dosing rate • Inverter control - – variable dosing over a range by manual or feedback control – 4-20 mA loop or SCADA via inverter – Flow-pacing
    11. 11. Linear Speed/Flow Characteristic •This is the key parameter for variable speed dosing applications - to increase the flow by 10%, increase the pump speed by 10% Speed - Flow Relationship for VF25 0 200 400 600 800 1000 1200 1400 1600 1800 0 10 20 30 40 50 60 70 80 90 100 RPM Flow(litres/hour)
    12. 12. Polymer & Coagulant Dosing • Many polymers & coagulants are highly shear sensitive • PC and other pumps will reduce particle size by around 50 to 70%, increasing coagulation time and polymer usage and reducing throughputs • The gentle pumping action of peristaltic pumps maintain particle size and maintain designed performance
    13. 13. •Breweries – Diatomaceous earth – Kiezelguhr – Brine solutions (salt water) – Yeast after storage (Gelager) – Yeast after fermentation – Fresh yeast dosing – Additives for taste, extending shelf live – Polyvinyl Pirolidoom PVPP Filter •Wineries – Diatomaceous earth with yeast – Wine dust •Flavoring – Adding flavors and colors… other additives.

    44. 44. Dosing Activated Carbon into Smoke Stacks 2 x VF32 pumps dose (abrasive) activated carbon slurry as part of an exhaust gas dioxin removal system at a waste incineration plant Typical carbon concentration is 15-20% by volume. Environmental regulators insist if the pumps don’t run then the plant doesn’t run either!
    45. 45. Bacterial Dosing in Soil Remediation  10 Verderflex pumps are used to dose live bacteria for toxic soil remediation in Germany The bacteria is highly shear sensitive and the gentle pumping action maintains a high live content to maximise treatment effectiveness

    51. 51. Space Age ? • A Verderflex pumps cleaning liquid for the world’s most powerful telescope on earth at the European space Observatory in Chile • The pump was chosen because - it is self-priming - has no seals ( the pump is only used once a year) - only the hose is exposed to cleaning solution - the pump self primes and - can run dry
    52. 52. Summary  Verderflex pumps can be used in many applications in many industries  Look for one of the key signs for an existing pump problem as the VF is often used to solve existing problems
